The city's name comes from an old Creek community in Alabama. Members of that community were expelled from Alabama by the United States government, along the Trail of Tears in the 1830s. The Creek founded a new community in the Indian Territory, and named it after their old settlement in Alabama. The town's Creek name was Rekackv (pronounced thlee-Kawtch-kuh), meaning broken arrow. The new Creek settlement was located several miles south of present-day downtown Broken Arrow.

In 1902 the Missouri–Kansas–Texas Railroad planned a railroad through the area and was granted town site privileges along the route. They sold three of the as-yet-unnamed sites to the Arkansas Valley Town Site Company. William S. Fears, secretary of that company, was allowed to choose and name one of the locations. He selected a site about 18 miles (29 km) southeast of Tulsa and about five miles north of the thlee-Kawtch-kuh settlement and named the new town site Broken Arrow, after the Indian settlement. The MKT railroad, which was completed in 1903, ran through the middle of the city. It still exists today and is now owned by Union Pacific which currently uses it for freight.
