Mounds is a town in Creek County, Oklahoma, United States. It is located just south of Tulsa; the town's population was 932 at the 2020 census.
The post office for this community was established in 1895 and originally named "Posey", for the Creek poet Alexander Posey, who lived in Eufaula, Oklahoma. In 1898, the town was moved southwest and renamed "Mounds" for twin hills that were nearby. By 1901, the St. Louis, Oklahoma and Southern Railway (later the St. Louis and San Francisco Railway) built a track through Mounds, and the town became an important cattle shipping point. Mounds incorporated as a city in the same year. The discovery of oil in the Glenn Pool field in 1905 turned Mounds into a shipping point for crude oil instead of cattle.
In the early days, Mounds was on the route of the Sapulpa & Interurban Railway (“S&I”) streetcar/interurban line connecting to Tulsa through Sapulpa, Kiefer and Glenpool; S&I subsequently went through a series of mergers and name
