The 1996 Gangneung submarine infiltration incident began on 18 September 1996, near the South Korean city of Gangneung when North Koreans abandoned their grounded submarine, and hid within the city resulting in 49 day long manhunt for the belligerents.

The incident was one of the more serious instances of North Korean espionage involving the Reconnaissance Bureau (reconnaissance team and 22nd Squadron of the Maritime Department of the Reconnaissance Bureau). The raid was launched by North Korean armed spies to assassinate the President of South Korea, Kim Young-sam, during his visit to Chunchon, on 5 October 1996.

Months after the start of the incident North Korea issued a rare apology for the events and ensuing loss of life.
