German submarine U-39 was a Type IXAU-boat of the Kriegsmarine that operated from 1938 to the first few days of World War II.

She was ordered by the Kriegsmarine on 29 July 1936 as part of the re-armament program (Aufrüstung) in Germany, which was illegal under the terms of the Treaty of Versailles. The keel for U-39 was laid down on 2 June 1937, by DeSchiMAG AG Weser of Bremen. She was commissioned on 10 December 1938 with Kapitänleutnant Gerhard Glattes in command.

On 14 September 1939, just 27 days after she began her first patrol, U-39 attempted to sink the British aircraft carrier HMS Ark Royal by firing two torpedoes at her. The U-39 was immediately hunted down by three British destroyers, disabled with depth charges, and subsequently sunk. All of the crew members survived and were captured.

U-39 was the first German U-boat to be sunk in World War II.

As one of the eight original German Type IX submarines, later designated IXA, U-39 had a displacement of 1,032 tonnes (1,016 long tons) when at the surface and 1,153 tonnes (1,135 long tons) while submerged. The U-boat had a total length of 76.50 m (251 ft), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.51 m (21 ft 4 in), a height of 9.40 m (30 ft 10 in), and a draught of 4.70 m (15 ft 5 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 metric horsepower (740 kW; 990 shp) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
