The Indo-Pakistani Naval War of 1971 refers to the maritime military engagements between the Indian Navy and the Pakistan Navy during the Indo-Pakistani War of 1971. The series of naval operations began with the Indian Navy's exertion of pressure on Pakistan from the Indian Ocean, while the Indian Army and Indian Air Force moved in to choke Pakistani forces operating in East Pakistan on land. Indian naval operations comprised naval interdiction, air defence, ground support, and logistics missions.

With the success of Indian naval operations in East Pakistan, the Indian Navy subsequently commenced two large-scale operations: Operation Trident and Operation Python. These operations were focused on West Pakistan, and preceded the start of formal hostilities between India and Pakistan.
