The Hall of Great Westerners was established by the National Cowboy & Western Heritage Museum in 1958. Located in Oklahoma City, Oklahoma, U.S., the Hall was created to celebrate the contributions of more than 200 men and women of the American West. Inductees include explorers, Native American leaders, writers, poets, politicians, statesmen and others.

The National Cowboy & Western Heritage Museum is a museum in Oklahoma City, Oklahoma, United States, with more than 28,000 Western and Native American art works and artifacts. The facility also has the world's most extensive collection of American rodeo photographs, barbed wire, saddlery, and early rodeo trophies. Museum collections focus on preserving and interpreting the heritage of the American West. The museum becomes an art gallery during the annual Prix de West Invitational Art Exhibition and Sale each June. The Prix de West Artists sell original works of art as a fund raiser for the museum. The expansion and renovation was designed by Curtis W. Fentress, FAIA, RIBA of Fentress Architects.
