Tillman County is a county located in the southwestern part of Oklahoma. As of the 2010 census, the population was 7,992. The county seat is Frederick.


The Medicine Lodge Treaty of 1867 established a reservation in the southwestern part of Indian Territory for the Kiowa, Apache and Comanche tribes. The Jerome Commission started enrolling members of these tribes in 1892, a prerequisite to opening "excess" land for settlement by non-Indians. The first lottery was held on August 6, 1901. It was followed in 1906 by the "Big Pasture" Lottery.

The county was founded at the time of Oklahoma statehood in 1907, and was named for Senator Benjamin Tillman of South Carolina. It had previously been part of Comanche County, Oklahoma Territory. Frederick was designated as the county seat at the time of statehood. In 1910 and 1924 portions of Kiowa County were added to the north side of the county.


According to the U.S. Census Bureau, the county has a total area of 879 square miles (2,280 km2), of which 871 square miles (2,260 km2) is land and 8.1 square miles (21 km2) (0.9%) is water. It is located along the Texas border.
