Robert Paul Prager (February 28, 1888 – April 5, 1918) was a German immigrant who was lynched in the United States during World War I as a result of Anti-German sentiment. He had worked as a baker in southern Illinois and then as a laborer in a coal mine, settling in Collinsville, a center of mining. At a time of rising anti-German sentiment, he was rejected for membership in the Maryville, Illinois local of the United Mine Workers of America. Afterward he angered area mine workers by posting copies of his letter around town that complained of his rejection and criticized the local president.
