SM UB-29 was a German Type UB II submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 30 April 1915 and launched on 31 December 1915. She was commissioned into the German Imperial Navy on 18 January 1916 as SM UB-29.[Note 1]

The submarine sank 36 ships in 17 patrols for a total of 47,107 gross register tons (GRT).[5] UB-29 was supposedly sunk by two depth charges from HMS Landrail south of Goodwin Sands at 51°9′N 1°46′E / 51.150°N 1.767°E / 51.150; 1.767 on 13 December 1916 ,[2] although the location of its wreck discovered in Belgian waters, approximately 15 nm NW of Ostend, contradicts this claim. The Landrail might have mistaken UB-29 for another boat, possibly the UC-19.[6]

The UB-29's wreckage – exceptionally well preserved and with the hull still intact – was found by Belgian divers in the summer of 2017, and formally identified in November 2017. Its exact location was not published, in order to enable further research and protection of the site.[7]
