Silas Stillman Soule (/soʊl/ SOHL; July 26, 1838 – April 23, 1865) was an American abolitionist, military officer and 'conductor' on the Underground Railroad. As a Kansas Jayhawker, he supported and was a proponent of John Brown's movement in the time of strife leading up to the American Civil War.

During the war, Soule joined the Colorado volunteers, and rose to the rank of captain in the Union Army. Soule was in command of 1st Colorado Cavalry, Company D that was present at Sand Creek and the massacre of Native Americans that occurred there on November 29, 1864. He testified at a U.S. military hearing that convened in February 1865 to investigate the event. Soule was murdered two months later in what some believed was retaliation.
