Dudley Walker Morton (July 17, 1907 – October 11, 1943) was a submarine commander of the United States Navy during World War II. He was commander of USS Wahoo (SS-238) during its third through seventh patrols. Wahoo was one of the most-celebrated submarines of World War II, sinking at least 19 Japanese ships, more than any other submarine of the time. Morton and Wahoo disappeared in 1943 during a patrol near La Perouse Strait, and was ultimately declared deceased three years later.
