HNLMS Bantam (Dutch: Hr.Ms. Bantam) was an ABC-class auxiliary minesweeper (HMV 4) of the Royal Netherlands Navy that was scuttled by her crew during World War II. She was later re-floated and repaired by the Japanese and converted into auxiliary submarine chaser Cha-117 or No. 117 (Japanese: 第百十七號驅潜特務艇).
