Hermon Franklin Titus (1852–1931) was an American socialist activist and newspaper publisher. Originally a Baptist minister before becoming a medical doctor, Titus is best remembered as a factional leader of the Washington state affiliate of the Socialist Party of America (SPA) during the first decade of the 20th century and as editor of The Socialist, one of the most-widely circulated radical newspapers of that period. Titus led a party split from the Socialist Party of Washington in 1909 and helped found a short-lived organization called the Wage Workers Party. His paper failed with that organization and he died in self-chosen obscurity in New York City, a medical doctor working in a low paying service job.
