Komahashi (駒橋), was an auxiliary vessel operated by the Imperial Japanese Navy, serving from the 1910s through World War II. Her classification changed numerous times during her operational life. Although officially designated as a submarine tender for most of her career, Komahashi very rarely functioned in this role, but was used instead as an oceanographic survey vessel throughout the Pacific, and as a kaibokan escort vessel for convoys of merchant ships during the Pacific War.
