Siloam Springs is a city in Benton County, Arkansas, United States. The city shares a border on the Arkansas- Oklahoma state line with the city of West Siloam Springs, Oklahoma, which is within the Cherokee Nation territory. The town was founded in 1882 and was characterized by the purported healing powers of the spring water feeding Sager Creek and trading with nearby Native American tribes. John Brown University (JBU) was founded in 1919 as a private, interdenominational, Christian liberal arts college in the city. Today, Siloam Springs is known for its efforts to preserve and revitalize the city's historic downtown and as a promoter of the arts via Sager Creek Arts Center and the JBU art gallery. The community is located on the western edge of the growing Northwest Arkansas metropolitan area and has had a population increase of 47% to 15,039 between the 2000 and 2010 censuses. 
In 2012, the city was named one of the 20 best small towns in America by Smithsonian magazine 
Osage Indians were the known first inhabitants of the area. Siloam Springs' first white settlers were of German and Scots-Irish origin. Simon Sager is considered the founder of the town, then known as Hico. 
The area is located in the Mid-South region of the country where the southern plains meet the Ozark Mountains. The city sits atop a plateau with many dogwood trees growing across the landscape. Siloam Springs is made up of Siloam Springs, Arkansas, and West Siloam Springs, Oklahoma. The latter is in the territory of the Cherokee Nation in northeastern Oklahoma.
A perennial creek, named after the founder, Sager Creek, flows through the downtown area.
According to the United States Census Bureau, the city has a total area of 11.2 square miles (28.9 km2), of which 11.1 square miles (28.7 km2) is land and 0.077 square miles (0.2 km2), or 0.71%, is water. 
The Fayetteville–Springdale–Rogers Metropolitan Area consists of three Arkansas counties: Benton, Madison, and Washington, and McDonald County, Missouri.  The area had a population of 347,045 at the 2000 census which had increased to 463,204 by the 2010 Census (an increase of 33.47 per cent). Siloam Springs is at the extreme western edge of this area, connected to the principal cities by Highway 412.

January is the coldest month with an average high of 44.3 °F (6.8 °C) and an average low of 24.2 °F (−4.3 °C).

The spring wet season is more pronounced than fall, with the highest rainfall in May. This differs slightly from the climate in central Arkansas, where the fall wet season is more comparable to spring.

Siloam Springs traffic is primarily served by US 412 (US 412) for east-west travel, connecting the city to Tulsa, Oklahoma, to the west via the Cherokee Turnpike and to Bentonville, Fayetteville, and Springdale, Arkansas, to the east. US 59 runs south from West Siloam Springs to Stilwell and Sallisaw, Oklahoma, while Arkansas 59 runs north to Gravette and south to Van Buren and Fort Smith, Arkansas. Within the city, major routes include Cheri Whitlock Drive, Lincoln Street, Main Street, Mount Olive Street, and University Street.
The city's primary water source is the Illinois River, although some water is purchased from Benton - Washington Regional Public Water Authority, whose source is Beaver Lake.  The water is treated with chlorine, and the by-products of this chlorination process are kept compliant with the Arkansas Department of Health standards. Fluoride is added to supplement the naturally occurring amount present prior to treatment.
Wastewater is treated at the Siloam Springs Wastewater Treatment Plant (SSWWTP). Since effluent is discharged into a tributary of the Illinois, the plant's effluent is required to meet the treatment standards of both Arkansas and Oklahoma. The phosphorus load of the Illinois has been subject of controversy in the area, even reaching the United States Supreme Court in 1992. The Environmental Protection Agency (EPA) has classified the Illinois as Section 303(d) of the Clean Water Act, listing it as an "impaired and threatened water" due to the high phosphorus loads.  As a result of the applicable strict phosphorus effluent regulations, SSWWTP upgraded its system in 2011. The upgrades also increased capacity 25% to 5.5 million gallons per day (MGD) (14,474 liters per hour).  Although presently a traditional biological nutrient removal (BNR) plant capable of meeting the interim phosphorus limit, pilot tests have proven a chemical nutrient removal (CNR) and membrane biological reactor combination to be effective well below the possible future permit limit. However, due to the high cost, these phases have been delayed. Currently, a 3-year study is being conducted to determine the background phosphorus level in the Illinois. The future effluent limits will likely be written following the conclusion of the study. An EPA Total maximum daily load (TMDL) study in the watershed is also ongoing.
