SM UB-34 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 22 July 1915 and launched on 5 December 1915. She was commissioned into the German Imperial Navy on 10 June 1916 as SM UB-34.

UB-34 sank 31 ships in 21 patrols. They included the William Cory and Son collier SS Hurstwood, which UB-34 torpedoed and sank in the North Sea off Whitby on 5 February 1917.

The submarine served in the Training Flotilla at the end of the war and was surrendered on 26 November 1918 in accordance with the requirements of the Armistice with Germany. UB-34 was broken up in Canning Town in 1922.
