The Keeper of the Plains is a 13.4 metres (44 ft) Cor-Ten steel sculpture by Kiowa-Comanche artist Blackbear Bosin.

The sculpture, commissioned by the city and private organizations to mark the United States Bicentennial, was erected in 1974.

From 1993 through 2004, an image of the statue, along with the words "Keeper of the Plains," appeared on the tails of Boeing KC-135 air refueling tankers assigned to the 22nd ARW.

The Keeper of the Plains was mentioned by Christian musician Rich Mullins in his 1991 song "Calling Out Your Name".

On March 11, 2021, a photo of the statue was shown as part of a clue on U.S. landmarks on Jeopardy!.
