Sayles Jenks Bowen (7 October 1813 – 16 December 1896) son of Josiah Bowen and Deborah Jenks, was the twentieth Mayor of Washington City, District of Columbia, from 1868 to 1870 and, as of 2022, the last Republican mayor in the District of Columbia or any of its sub-jurisdictions. Bowen was one of the most controversial mayors in the history of the American capital, because of his outspoken support of emancipation and racial integration.
