German submarine U-435 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 11 April 1940 by F Schichau GmbH in Danzig as yard number 1477, launched on 31 May 1941 and commissioned on 30 August 1941 under Korvettenkapitän Siegfried Strelow (Knight’s Cross).

The boat's service began on 30 August 1941 with training as part of the 5th U-boat Flotilla. She was transferred to the 1st flotilla on 1 January 1942 for active service and then to the 11th flotilla on 1 July 1942. She returned to the 1st flotilla on 1 February 1943.

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-435 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
