The keel for this boat was laid down on 30 August 1940 at the Deutsche Schiff und Maschinenbau AG, Bremen yard as 'werk' 704. She was launched on 15 August 1941 and commissioned on 3 February 1942 under the command of Fregattenkapitän Eberhard Hoffmann.

The U-boat's service began with training as part of the 4th U-boat Flotilla. She then moved to the 10th flotilla on 1 September 1942 for operations. She sank two ships, totalling, one auxiliary warship of 358 tons and damaged three others, for 14,499 tons. She also damaged one auxiliary warship (7,252 tons).

Patrol and loss
The submarine's only patrol took her from Kiel on 7 August 1942, across the North Sea and into the northern Atlantic Ocean via through the gap between Iceland and the Faroe Islands to the Gulf of the St. Lawrence. Her first victims were the USS Laramie and the Arlyn; both damaged at the northern end of the Belle Isle Strait on 28 August. She went on to attack the Aeas on 6 September, HMCS Raccoon on the 7th, the Essex Lance on the 16th and the Pan York, also on the 16th.

U-165 had almost reached the French Atlantic ports when she was sunk on 27 September 1942 by a Vickers Wellington of 311/Q Squadron, RAF just west of the Bay of Biscay.
