Harry B. Hawes (November 15, 1869-July 31, 1947) was an American politician who served as a Democratic member of the U.S. House and the U.S. Senate from Missouri. Born in Covington, Kentucky, Hawes moved to St. Louis, Missouri, where he graduated from Washington University School of Law in 1896, and began his career in law. He represented the Republic of Hawaii when it was annexed to the US. He later served as president of the St. Louis Police Board.
Hawes entered the Missouri House of Representatives in 1916, but left to serve in World War I. In the election of 1920, Hawes was elected to the US House, where he served until resigning on October 15, 1926. The following month he was elected to the Senate. Because Senator Selden P. Spencer had died, Hawes took his senate seat three months early, December 6, 1926. He resigned on February 3, 1933, to focus on wildlife conservation and law.
Hawes died in Washington, DC.
