A post office was established at Wister, Indian Territory on June 30, 1890. The community was named for an official of the Choctaw, Oklahoma and Gulf Railroad, one of the two railroads which intersected in the town. At the time of its founding, Wister was located in Sugar Loaf County, a part of the Moshulatubbee District of the Choctaw Nation. Until becoming known as Wister, the settlement had been known as Wister Junction, due to its location at the crossing of two railroad routes. The Choctaw, Oklahoma and Gulf Railroad was an east-west route linking Wister Junction with McAlester, and passing through lucrative coal mining towns along the way. Its eastern terminus was at the St. Louis and San Francisco Railroad, a north-south route connecting Fort Smith, Arkansas with Paris, Texas. After receiving its post office the town could no longer be known as Wister Junction, as federal post office regulations forbade new post offices from carrying descriptive names such as "Junction," "Mountain," or "Corner."
