Oklahoma City will mark National Indigenous Peoples Day on Monday, Oct. 12, with a full-day celebration at the First Americans Museum—the first observance since the City Council made the holiday permanent last month. The designation establishes the second Monday in October as the annual date. In past years, Mayor David Holt recognized the day through proclamations. Monday’s museum events will run from 10 a.m. to 4 p.m. and include work by local artists, remarks from Holt, and soccer and lacrosse activities. Outdoor activities are free; museum admission will be discounted. Marci Hensley, the museum’s public programs manager, said the observance should recognize Indigenous communities and stories beyond Oklahoma’s 39 tribes. She described the city’s permanent designation as meaningful progress, while noting that more work remains to be done. The museum’s celebration will highlight Indigenous cultures as well as the difficult histories and struggles that shaped the present, Hensley said.
