I-124, originally named Submarine Minelayer No. 52 and then named I-24 from before her launch until June 1938, was an I-121-class submarine of the Imperial Japanese Navy that served during the Second Sino-Japanese War and World War II. During the latter conflict, she operated in support of the Japanese invasion of the Philippines and was sunk during anti-shipping operations off Australia in January 1942.

After she was renumbered I-124 in 1938, the number I-24 was assigned to a later submarine which also served during World War II.
