Captain Benjamin Walker (1753–January 13, 1818) was a soldier in the American Revolutionary War and later served as a U.S. Representative from New York. During the American Revolutionary War, he was an aide-de-camp to General Friedrich Wilhelm von Steuben (during this appointment he was reputed to have been the male companion of the Baron) and subsequently as a member of the staff of General George Washington. From March 21, 1791 until February 20, 1798, Walker served as a captain and as naval officer of customs at the port of New York. He was moved to Fort Schuyler, now Utica, in New York State, in 1797. He also worked as an agent of the great landed estate of the Earl of Bath. Walker was elected as a Federalist to the Seventh Congress (March 4, 1801 - March 3, 1803). After his tenure, he declined to be a candidate for re-nomination in 1802. Walker died in Utica, New York, on January 13, 1818.
