Anthony Petit (died 1946) was an American lighthouse keeper. In 1945 he was assigned to the Scotch Cap Light in Alaska as the head of a five-man crew. All of the men were killed on April 1, 1946 when a massive tsunami, created by an earthquake, struck the station, destroying it.
The United States Coast Guard has named a USCG coastal buoy tender (WLM 558) based in Ketchikan, Alaska in his honor.
