Robert H. Waterman (March 4, 1808 – August 8, 1884), known as Bully Waterman or Bully Bob Waterman, was an American merchant sea captain. He set three sailing speed records; his time of 74 days from Hong Kong to New York City has never been bettered in a sail-powered vessel. He was reputed as a martinet, and was once convicted of assault against a crewman in a controversial California criminal case.
