The Japanese submarine I-165 (I-65, until 20 May 1942) was a Kaidai type of cruiser submarine active in World War II. A KD5 sub-class boat, I-165 was built for the Imperial Japanese Navy (IJN) during the early 1930s.

The submarines of the KD5 sub-class were improved versions of the preceding KD4 sub-class. They displaced 1,732 tonnes (1,705 long tons) surfaced and 2,367 tonnes (2,330 long tons) submerged. The submarines were 97.7 meters (320 ft 6 in) long, had a beam of 8.2 meters (26 ft 11 in) and a draft of 4.7 meters (15 ft 5 in). The boats had a diving depth of 75 m (246 ft)

For surface running, the boats were powered by two 3,400-brake-horsepower (2,535 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 900-horsepower (671 kW) electric motor. They could reach 20 knots (37 km/h; 23 mph) on the surface and 8 knots (15 km/h; 9.2 mph) underwater. On the surface, the KD5s had a range of 10,800 nautical miles (20,000 km; 12,400 mi) at 10 knots (19 km/h; 12 mph); submerged, they had a range of 60 nmi (110 km; 69 mi) at 3 knots (5.6 km/h; 3.5 mph).

The boats were armed with six internal 53.3 cm (21.0 in) torpedo tubes, four in the bow and two in the stern. They carried a total of 14 torpedoes. They were also armed with one 100 mm (3.9 in) deck gun for combat on the surface, as well as a 13.2 mm (0.52 in) anti-aircraft machinegun.

Built at the Kure Naval Arsenal, laid down as I-65 on 19 December 1929, launched on 2 June 1931 and completed on 1 December 1932. Lt Cdr Hankyu Sasaki was her first commanding officer and she was assigned to Submarine Division 30. On 20 August 1941, just prior to the outbreak of the war in the Pacific, Lt Cdr Harada Hakue is appointed commanding officer. She was part of the 5th Submarine Squadron.
