The region Northeast Ohio, in the US state of Ohio, in its most expansive usage contains six metropolitan areas ( Cleveland–Elyria, Akron, Canton–Massillon, Youngstown–Warren, Mansfield, and Weirton–Steubenville) along with eight micropolitan statistical areas. Most of the region is considered either part of the Cleveland–Akron–Canton, OH Combined Statistical Area and media market or the Youngstown–Warren, OH-PA Combined Statistical Area and media market. In total the region is home to 4,529,596 residents. Northeast Ohio also includes most of the area known historically as the Connecticut Western Reserve. In 2011, the Intelligent Community Forum ranked Northeast Ohio as a global Smart 21 Communities list.  It has the highest concentration of Hungarian Americans in the United States. 
Different sources define the region as having various boundaries. At its largest, there are 23 counties in the region, home to over 4.5 million people, with a labor force of almost 2.2 million and an economic GDP (nominal) of $195 billion, which makes it comparable to that of New Zealand or the Republic of Ireland.  
Most of Northeast Ohio is part of the Cleveland–Akron–Canton Combined Statistical Area, which ranked as the 17th-largest Combined Statistical Area (CSA) in the United States as of the 2010 Census with a population of 3,630,166.

In the 1950s, AT&T assigned most of Northeast Ohio area code 216. The western half of the region, including Ashland and Richland counties, and parts of Huron, Wayne and Erie counties, was assigned area code 419. In 1996, area code 216 was reduced in size to cover the northern half of its prior area, centering on Cleveland. Area code 330 was introduced for the southern half of Northeast Ohio, including Summit, Portage, Medina, Stark, Columbiana and Mahoning counties, and much of Wayne, Trumbull and Tuscarawas counties.
In 1997, area code 216 was further split as the need for additional phone numbers grew. Area code 216 was again reduced in geographical area to cover the city of Cleveland and its inner ring suburbs. Area code 440 was introduced to cover the remainder of was what previously area code 216, including all of Lake, Lorain, Ashtabula and Geauga counties, and parts of Trumbull, Huron, Erie and Cuyahoga counties. Some communities, such as Parma and Parma Heights, were divided into multiple area codes. In 1999, Congressman Dennis Kucinich introduced federal legislation to protect small and medium-sized cities from being split into two or more area codes.  
In 2000, it was anticipated that the available phone numbers in area code 330 would be exhausted, and an overlay area code was introduced. Area code 234 was assigned to overlap existing area code 330. With the creation of area code 234, any new phone number in the geographical area formerly covered by area code 330 could be assigned a phone number in either the 234 or 330 area codes, with no change in local or long distance toll status. This made necessary the use of ten-digit dialing within the 330/234 area code region. After the introduction of area code 234, assignments of new telephone numbers in the area did not continue at an accelerated pace, and new phone numbers for area code 234 were not assigned until 2003.
