SM UB-57 was a German Type UB III submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. She was commissioned into the Flanders Flotilla of the German Imperial Navy on 30 July 1917 as SM UB-57.[Note 1]
She operated as part of the Flanders Flotilla based in Zeebrugge. UB-57 was thought to have sunk with all hands at 23:00 on 14 August 1918 at 51°56′N 02°02′E after striking a mine,[3] but on April 14th 2025, an already marked wreck at a depth of 17 meters, just west of the Westhinder shoal, close to the border with France was formally identified as the UB-57.[4]
