INS Khukri was a British Type 14 (Blackwood-class) frigate of the Indian Navy. She was sunk off the coast of Diu, Gujarat, India by the Pakistan Navy Daphné-class submarine Hangor on 9 December 1971 during the Indo-Pakistani War of 1971. This was the first warship sunk in action by a submarine since World War II. It remains the post-Independence Indian navy's only warship to be lost in war to date.

After the beginning of hostilities on 3 December 1971, Indian Naval radio detection equipment identified a submarine lurking about 35 miles (56 km) south-west of Diu harbour. The 14th Frigate Squadron of the Western Fleet was dispatched to destroy the submarine. It normally consisted five ships Khukri, Kirpan , Kalveti, Krishna and Kuthar, but at the time of the incident Kuthar's boiler room was being repaired in Bombay. One reason that may have prompted the decision to deploy two obsolete Blackwood-class frigates against a modern Daphne-class submarine was that the Indian Navy lacked sufficient numbers of anti-submarine aircraft.
