The Japanese submarine I-14 was a Type AM submarine built for the Imperial Japanese Navy (IJN) during World War II.

The Type AM submarines were versions of the preceding A2 class-class with the command facilities replaced by an enlarged aircraft hangar were fitted for a pair of Aichi M6A1 floatplane bombers. They displaced 3,661 tonnes (3,603 long tons) surfaced and 4,838 tonnes (4,762 long tons) submerged. The submarines were 113.7 meters (373 ft 0 in) long, had a beam of 11.7 meters (38 ft 5 in) and a draft of 5.9 meters (19 ft 4 in). They had a diving depth of 100 meters (330 ft).

For surface running, the boats were powered by two 2,200-brake-horsepower (1,641 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 300-horsepower (224 kW) electric motor. They could reach 16.75 knots (31.02 km/h; 19.28 mph) on the surface and 5.5 knots (10.2 km/h; 6.3 mph) underwater. On the surface, the AMs had a range of 21,000 nautical miles (39,000 km; 24,000 mi) at 16 knots (30 km/h; 18 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 bow 53.3 cm (21.0 in) torpedo tubes and carried a total of a dozen torpedoes. They were also armed with a single 14 cm (5.5 in) deck gun and two triple and one single mount for 25 mm (1 in) Type 96 anti-aircraft guns.
