Jenks is a city in Tulsa County, Oklahoma, United States, and a suburb of Tulsa, in the northeastern part of the state. It is situated between the Arkansas River and U.S. Route 75. Jenks is one of the fastest growing cities in Oklahoma. The city's population was 9,557 in the 2000 census, but by 2010, the population was 16,924, an increase of 77.1 percent. The Census estimated Jenks' population as 23,767 in 2019.
Jenks began in 1904 as a community site established by the Midland Valley Railroad between Tulsa and Muskogee, alongside the Arkansas River. Though the river could only be utilized by shallow draft steamboats while the water level was up, these two transportation routes proved vital to Jenks' early development.
Jenks was named after William Henry Jenks the owner and director of the Midland Valley Railroad. According to a 1957 article in the Tulsa Tribune, an agent for the townsite company was told by the railroad home office to name a town for the director.
The town was officially platted on July 15, 1905. Also in 1905, a major petroleum discovery was made, further bolstering the economy of the area. The "Glenn Pool" oil well and subsequent oil claims brought many business people to the general area.
