Robert Johns Bulkley (October 8, 1880 - July 21, 1965) was a United States Democratic Party politician from Ohio. He served in the United States House of Representatives and U.S. Senate.
A graduate of Harvard University for undergraduate studies and law school, Bulkley commenced the practice of law in Cleveland, Ohio in 1906. Bulkley served two terms in the House from 1911-1915 from the 21st District on Cleveland's East Side. He was later elected to the U.S. Senate in 1930 to fill the vacancy created by the death of Theodore E. Burton. Bulkley was re-elected in 1932, but lost a bid for a second full term in 1938 to Robert A. Taft.
