The Research Triangle, commonly referred to as simply The Triangle, is a region in the Piedmont of North Carolina in the United States, anchored by the three major research universities of North Carolina State University, Duke University, and University of North Carolina at Chapel Hill, as well as the cities of Raleigh and Durham and the town of Chapel Hill. The eight-county region, officially named the Raleigh–Durham–Chapel Hill combined statistical area (CSA), comprises the Raleigh and Durham–Chapel Hill metropolitan areas and the Dunn, Henderson, Oxford, and Sanford Micropolitan Statistical Areas.
A 2017 Census estimate put the population at 2,156,253, making it the second largest metropolitan area in the state of North Carolina behind Charlotte.  The Raleigh–Durham television market includes a broader 24-county area which includes Fayetteville, North Carolina, and has a population of 2,726,000 persons. 
The "Triangle" name was cemented in the public consciousness in the 1950s with the creation of Research Triangle Park, home to numerous high-tech companies and enterprises. Although the name is now used to refer to the geographic region, "the Triangle" originally referred to the universities, whose research facilities, and the educated workforce they provide, have historically served as a major attraction for businesses located in the region.
The region is sometimes confused with The Triad, which is a North Carolina region adjacent to and directly west of the Triangle comprising Greensboro, Winston-Salem, and High Point, among other cities.

The Triangle region, as defined for statistical purposes as the Raleigh–Durham–Chapel Hill CSA, comprises eight counties, although the U.S. Census Bureau divided the region into two metropolitan statistical areas and one micropolitan area in 2003. The Raleigh metropolitan area comprises Wake,Franklin, and Johnston Counties; the Durham-Chapel Hill metropolitan area comprises Durham, Orange, Chatham, and Person Counties; and the Dunn micropolitan area comprises Harnett County.
Some area television stations define the region as Raleigh–Durham–Fayetteville. Fayetteville is more than 50 miles (80 km) from Raleigh, but is part of the Triangle television market.
Public secondary education in the Triangle is similar to that of the majority of the state of North Carolina, in which there are county-wide school systems (the exception is Chapel Hill-Carrboro City Schools within Orange County but apart from Orange County Schools). Based in Cary, the Wake County Public School System, which includes the cities of Raleigh and Cary, is the largest school system in the state of North Carolina and the 15th-largest in the United States, with average daily entollment of 159,949 as of the second month of the 2016-17 school year.  Other larger systems in the region include Durham Public Schools (about 33,000 students) and rapidly growing Johnston County Schools (about 31,000 students).

With the significant number of universities and colleges in the area and the relative absence of major league professional sports, NCAA sports are very popular, particularly those sports in which the Atlantic Coast Conference participates, most notably basketball.
The Duke Blue Devils (representing Duke University in Durham), NC State Wolfpack (representing North Carolina State University in Raleigh), and North Carolina Tar Heels (representing the University of North Carolina at Chapel Hill) are all members of the ACC. Rivalries among these schools are very strong, fueled by proximity to each other, with annual competitions in every sport. Adding to the rivalries is the large number of graduates the high schools in the region send to each of the local universities. It is very common for students at one university to know many students attending the other local universities, which increases the opportunities for "bragging" among the schools. The four ACC schools in the state, Duke, North Carolina, North Carolina State, and Wake Forest University (the last of which was originally located in the town of Wake Forest before moving to Winston-Salem in 1956), are referred to as Tobacco Road by sportscasters, particularly in basketball. All four teams consistently produce high-caliber teams. Each of the Triangle-based universities listed has won at least two NCAA Basketball national championships.
Three historically black colleges, including recent Division I arrival North Carolina Central University and Division II members St. Augustine College and Shaw University also boost the popularity of college sports in the region.
The region has only one professional team of the four major sports, the Carolina Hurricanes of the NHL, based in Raleigh. Since moving to the Research Triangle region from Hartford, Connecticut, they have enjoyed great success, including winning a Stanley Cup. With only one top-level professional sports option, minor league sports are quite popular in the region. The Durham Bulls in downtown Durham are a AAA Minor League baseball affiliate of the Tampa Bay Rays, and the Carolina Mudcats, based in Zebulon, 10 miles east of Raleigh, are the Advanced-A affiliate of the Milwaukee Brewers. In Cary, North Carolina FC plays in the second-level United Soccer League, and the North Carolina Courage began play in the National Women's Soccer League in 2017 after the owner of North Carolina FC bought the NWSL franchise rights of the Western New York Flash and relocated the NWSL franchise to the Triangle.

The area also had a team in the fledgling World League of American Football – however, the Raleigh–Durham Skyhawks, coached by Roman Gabriel, did not exactly cover themselves in glory; they lost all 10 games of their inaugural (and only) season in 1991. The team folded after that, being replaced in the league by the Ohio Glory, which fared little better at 1-9, ultimately suffering the same fate – along with the other six teams based in North America – when the league took a two-year hiatus, returning as a six-team all-European league in 1995.
With over 1200 active participants in multiple recreation centers and university campuses throughout the area, Research Triangle is home to one of the largest badminton communities in the Southeastern United States. The American Badminton Academy is also located here in a dedicated facility with seven permanent courts. The Academy is unique among U.S. badminton facilities in that it hosts an international player development program run by Dennis Christensen, an Olympic-level coach from Denmark.
Anchored by leading technology firms, government and world-class universities, medical centers and schools, the area's economy has performed exceptionally well. Significant increases in employment, earnings, personal income, and retail sales are projected over the next 15 years.
The region's growing high-technology community includes such companies as IBM, SAS Institute, Cisco Systems, NetApp, Red Hat, EMC Corporation, and Credit Suisse First Boston. In addition to high-tech, the region is consistently ranked in the top three in the U.S. with concentration in life science companies. Some of these companies include GlaxoSmithKline, Biogen Idec, BASF, Merck & Co., Novo Nordisk, Novozymes, and Pfizer. Research Triangle Park and North Carolina State University's Centennial Campus in Raleigh support innovation through R&D and technology transfer among the region's companies and research universities (including Duke University and the University of North Carolina at Chapel Hill).
The area fared relatively well during the late-2000s recession, ranked as the strongest region in North Carolina by the Brookings Institution and among the top 40 in the country. The change in unemployment during 2008 to 2009 was 4.6% and home prices was 2%. The Greensboro metropolitan area was listed among the second-weakest and the Charlotte area among the middle in the country.

The Triangle proper is served by three major interstate highways: I-40, I-85, and I-87 along with their spurs: I-440 and I-540, and seven U.S. Routes: 1, 15, 64, 70, 264, 401, and 501. US Highways 15 and 501 are multiplexed through much of the region as US 15-501. I-95 passes 30 miles east of Raleigh through Johnston County, with I-87 connecting I-95 at Rocky Mount, NC to Raleigh via the US 64-264 Bypass.
The two interstates diverge from one another in Orange County, with I-85 heading northeast through northern Durham County toward Virginia, while I-40 travels southeast through southern Durham, through the center of the region, and serves as the primary freeway through Raleigh. The related loop freeways I-440 and I-540 are primarily located in Wake County around Raleigh. I-440 begins at the interchange of US 1 and I-40 southwest of downtown Raleigh and arcs as a multiplex with US 1 northward around downtown with the formal designation as the Cliff Benson/Raleigh Beltline (cosigned with US 1 on three-fourths of its northern route) and ends at its junction with I-40 in southeast Raleigh. I-540, sometimes known as the Raleigh Outer Loop, extends from the US 64-264 Bypass to I-40 just inside Durham County, where it continues across the interstate as a state route (NC 540), prior to its becoming a toll road from the NC 54 interchange to the current terminus at NC Highway 55 near Holly Springs. I-95 serves the extreme eastern edge of the region, crossing north-south through suburban Johnston County.
U.S. Routes 1, 15, and 64 primarily serve the region as limited-access freeways or multilane highways with access roads. US 1 enters the region from the southwest as the Claude E. Pope Memorial Highway and travels through suburban Apex where it merges with US 64 and continues northeast through Cary. The two highways are codesignated for about 2 miles (3.2 km) until US 1 joins I-440 and US 64 with I-40 along the Raleigh–Cary border. Capital Boulevard, which is designated US 1 for half of its route and US 401 the other is not a limited-access freeway, although it is a major thoroughfare through northeast Raleigh and into the northern downtown area.
North Carolina Highway 147 is a limited-access freeway that connects I-85 with Toll Route NC 540 in northwestern Wake County. The older, toll-free portion of the four-lane route—known as the Durham Freeway or the I.L. "Buck" Dean Expressway—traverses downtown Durham and extends through Research Triangle Park to I-40. The Durham Freeway is often used as a detour or alternate route for I-40 through southwestern Durham the Chapel Hill area in cases of traffic accident, congestion or road construction delays. The tolled portion of NC 147, called the Triangle Expressway—North Carolina's first modern toll road when it opened to traffic in late 2011—continues past I-40 to Toll NC 540. Both Toll NC 147 and Toll NC 540 are modern facilities which collect tolls using transponders and license plate photo-capture technology.
A partnering system of multiple public transportation agencies currently serves the Triangle region under the joint GoTransit branding. Raleigh is served by the Capital Area Transit (CAT) municipal transit system, while Durham has the Durham Area Transit Authority (DATA) system. Chapel Hill is served by Chapel Hill Transit, and Cary is served by C-Tran public transit systems. However, Triangle Transit, formerly called the Triangle Transit Authority (TTA), works in cooperation with all area transit systems by offering transfers between its own routes and those of the other systems. Triangle Transit also coordinates an extensive vanpool and rideshare program that serves the region's larger employers and commute destinations.
Plans have been made to merge all of the area's municipal systems into Triangle Transit, and Triangle Transit also has proposed a regional rail system to connect downtown Durham, downtown Cary and downtown Raleigh with multiple suburban stops, as well as stops in the Research Triangle Park area. The agency's initial proposal was effectively cancelled in 2006, however, when the agency could not procure adequate federal funding. A committee of local business, transportation and government leaders currently are working with Triangle Transit to develop a new transit blueprint for the region, with various modes of rail transit, as well as bus rapid transit, open as options for consideration. 
The General Assembly of North Carolina chartered the Raleigh–Durham Aeronautical Authority in 1939, which was changed in 1945 to the Raleigh–Durham Airport Authority. The first new terminal opened in 1955. Terminal A (now Terminal 1) opened in 1981. American Airlines began service to RDU in 1985.
RDU opened the 10,000-foot (3,000 m) runway, 5L-23R, in 1986. American Airlines opened its north-south hub operation at RDU in the new Terminal C in June 1987, greatly increasing the size of RDU's operations with a new terminal including a new apron and runway. American brought RDU its first international flights to Bermuda, Cancun, Paris and London.
In 1996, American Airlines ceased its hub operations at RDU due to Pan Am and Eastern Airlines. Pan Am and Eastern were Miami's main tenants until 1991, when both carriers went bankrupt. Their hubs at MIA were taken over by United Airlines and American Airlines. This created a difficulty in competing with US Airways' hub in Charlotte and Delta Air Lines' hub in Atlanta, Georgia for passengers traveling between smaller cities in the North and South. Midway Airlines entered the market, starting service in 1995 with the then somewhat novel concept of 50-seat Canadair Regional Jets providing service from its RDU hub primarily along the East Coast. Midway, originally incorporated in Chicago, had some success after moving its operations to the midpoint of the eastern United States at RDU and its headquarters to Morrisville, NC. The carrier ultimately could not overcome three weighty challenges: the arrival of Southwest Airlines, the refusal of American Airlines to renew the frequent flyer affiliation it had with Midway (thus dispatching numerous higher fare-paying businesspeople to airlines with better reward destinations), and the significant blow of September 11, 2001. Midway Airlines filed Chapter 11 bankruptcy on August 13, 2001, and ceased operations entirely on October 30, 2003.
In February 2000, RDU was ranked as the nation's second fastest-growing major airport in the United States, by Airports Council International, based on 1999 statistics. Passenger growth hit 24% over the previous year, ranking RDU second only to Washington Dulles International Airport. RDU opened Terminal A south concourse for use by Northwest and Continental Airlines in 2001. The addition added 46,000 square feet (4,300 m2) and five aircraft gates to the terminal. Terminal A became designated as Terminal 1 on October 26, 2008. In 2003, RDU also dedicated a new general aviation terminal. RDU continues to keep pace with its growth by redeveloping Terminal C into a new state-of-the-art terminal, now known as Terminal 2, which opened in October 2008. 
Carriers at RDU International Airport:
- Air Canada, the airport's first international carrier, introduced service to Toronto, Ontario, Canada in 1996.
- Southwest Airlines, the nation's largest low-cost carrier, began service to RDU in 1999.
- America West (merged with US Airways in 2005) began service at RDU in 2002 with flights to Phoenix and Las Vegas
- JetBlue began nonstop service between RDU and New York and Boston in 2006, with additional service to Fort Lauderdale, which began in January 2008.
