German submarine U-274 was a Type VIIC U-boat of the Nazi German Kriegsmarine during World War II.

The submarine was laid down on 9 January 1942 at the Bremer Vulkan yard at Bremen-Vegesack as 'werk' 39. She was launched on 19 September 1942 and commissioned on 7 November under the command of Oberleutnant zur See Günther Jordan.

Service history
U-274 served with the 8th U-boat Flotilla for training from November 1942 to July 1943 and operationally with the 7th U-boat Flotilla from 1 August 1943. She carried out two patrols, but sank no ships.

She carried out short voyages between Kiel in Germany and Bergen and Trondheim in Norway over August 1943.

1st patrol
The boat departed Trondheim on 1 September 1943 and returned to the Norwegian port twelve days later on the 13th.

2nd patrol and loss
For her second sortie, the boat headed toward the Atlantic Ocean, via the 'gap' between Iceland and the Faroe Islands. She was sunk by Hedgehog and depth charges dropped by the British destroyers HMS Duncan and Vidette and a B-24 Liberator of No. 224 Squadron RAF. The pilot of the Liberator was a Swiss national serving in the RAF. The intercom in the aircraft had been inadvertently left connected to the radio. As a result, ships of the nearby convoy escort heard an improvised commentary which was a great encouragement.
