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. As of the 2000 census, the city population was 9,557, but by 2010, the population was 16,924.
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.
