Creek National Capitol, which is also known as Creek Council House, is a building in Okmulgee, Oklahoma. It was capitol of the Muscogee or Creek nation when Oklahoma became a state. In 1919, the city of Okmulgee bought the building from the U.S. Department of the Interior. And in 1961, it was declared a National Historic Landmark.

The building is now the site of the Creek Council House Museum, which has artifacts and exhibits about the history of the Creek people and Native American arts and crafts. Since 2006, the Creek Nation had shown interest in buying back the building. In August 2010, the city of Okmulgee agreed to sell back the building to the tribe for $3 million.
