John Bennett (1959–2004) was a British SCUBA diver who is best known for setting a world record by becoming the first person to deep dive below a depth of 300 m (1,000 ft) on self-contained breathing apparatus on 6 November 2001.
Bennett founded Atlantis Tech at the Atlantis dive resort in the Philippines.
In the early 2000s, Bennett and Ron Loos made the first dives to the MV Princess of the Orient wreck site in Manila Bay.
In 2001 located the wreck of the Imperial Japanese Navy dreadnought Japanese battleship Yamashiro through sound scans, but could not confirm it before his death. Confirmation was not made until 2006.
John Bennett was missing, presumed dead on 15 March 2004 in a commercial diving incident in Korea. He was declared legally dead in 2006, but the body has never been recovered. Bennett was survived by his wife Gabby and their two children, Joshua and Katie.
