Post Oak is an unincorporated community in Carter County, Oklahoma, United States.

A Comanche Indian mission, Post Oak Mission, was established in 1896 in Post Oak by the Mennonite Brethren Churches of North America. In 1957, in order to make room for a missile range, the mission and its cemetery were relocated to Indiahoma. Today the mission is known as the Post Oak Mennonite Brethren Church.
