I-402 (伊号第四百二潜水艦, I-gō-dai yon-hyaku-ni-sensuikan) was an Imperial Japanese Navy Sentoku-type (or I-400-class) submarine commissioned in 1945 for service in World War II. Originally intended to be a submarine aircraft carrier like her sister ships I-400 and I-401, she instead was completed as a submarine tanker, but entered service less than a month before the end of the war and never carried out a tanker voyage. She surrendered to the United States at the end of the war in 1945 and was scuttled in 1946. Until 1965, the Sentaku-type submarines were the largest submarines ever commissioned.
