The Oklahoma History Center (OHC) is the history museum of the state of Oklahoma. Located on an 18-acre (7.3 ha) plot across the street from the Governor's mansion at 800 Nazih Zuhdi Drive in Oklahoma City, the current museum opened in 2005 and is operated by the Oklahoma Historical Society (OHS). It preserves the history of Oklahoma from ancient Native American tribal nations to the present day.
The OHC was founded in 1893 by members of the Territorial Press Association in Guthrie, Oklahoma, then the capital of Oklahoma, Territory, but moved to Oklahoma City after statehood was declared in November 1907.
