Adair County is a county located in the U.S. state of Oklahoma. As of the 2020 census, the population was 19,495.[1] Its county seat is Stilwell.[2] Adair County was named after the Adair family of the Cherokee tribe.[3] One source says that the county was specifically named for Watt Adair, one of the first Cherokees to settle in the area.[4] Adair County is part of the Cherokee Nation reservation.
The county was created in 1906 from the Goingsnake and Flint districts of the Cherokee Nation. There was a decade-long struggle over what town would become the county seat between Stilwell and Westville.[5] When the county was formed, Westville was identified as the county seat, due partly to its location at the intersection of two major railroads: the Kansas City Southern Railway and the St. Louis – San Francisco Railway.[6] The county seat was moved to Stilwell in 1910.[7]
During the Great Depression and World War II, strawberries became a major crop in Adair County. In 1948, the first Stilwell Strawberry Festival was organized. The 2002 festival saw some 40,000 people in attendance.[5]
The 1910 census counted 10,535 residents. By 1990, it was up to 18,421.
According to the U.S. Census Bureau, the county has a total area of, of which is land and (0.6%) is water.[8]
The county is part of the Ozark plateau uplift, the tree-covered foothills of the Boston Mountains.[9] North and central Adair County are drained by the Illinois River and three creeks.[9] Two more creeks lie near Stilwell.[9]

Less than 1 percent of the population was either Black or African American, Asian, or Pacific Islander, and 2.3 percent were identified as other. This makes it the only majority-minority county in Oklahoma. Adair county had a higher percentage of Native Americans (American Indians) in its population than any other Oklahoma county.[11] As of 2020, its population was 19,495.

Although most Native American counties tend to skew Democratic, the Cherokee Nation - which Adair County is a part of - has tended to be deeply Republican at the federal level for most its existence, though Southern Democrats have occasionally taken it in strong election years such as 1964 and 1976. No Democrat has won Adair County since Jimmy Carter in 1976.
The county is home to food processing and canning industries; poultry farms; cattle ranches; horse breeders; dog breeders, and strawberry fields.[13]
