The Indo-Pakistani Naval war of 1971 consisted of a series of naval battles fought between the Indian and Pakistani Navy during the Indo-Pakistani War of 1971. The battles were an integral part of India-Pakistan War and the Bangladesh Liberation War. The series of naval operations began by the Indian Navy to exert pressure from the seas while the Indian Army and Indian Air Force moved in to close the ring round East Pakistan from several directions on land. The naval operations incorporated the naval interdiction, air defence, ground support, and logistics missions.

With the success of the Indian Navy's operations in East Pakistan, the Indian Navy commenced two large-scale operations, Operation Trident and Operation Python in the Western front, prior to the start of formal combat between India and Pakistan.

The Indian Navy did not play a vital and integral role during the Indo-Pakistani War of 1965 as the war was more focused on the land based conflict. On 7 September, a flotilla of the Pakistan Navy under the command of Commodore S.M. Anwar, carried out a bombardment, Operation Dwarka, of the Indian Navy's radar station of Dwarka, 200 miles (300 km) south of the Pakistani port of Karachi. This operation caused the Indian Navy to undergo a rapid modernization and expansion. Consequently, the Indian Navy budget grew from 350 million to 1.15 billion. The Indian Navy's Combatant Fleet was augmented by the addition of a Submarine squadron with the acquisition of six Osa missile ship from the Soviet Union. The Indian Naval Air Arm was also strengthened.
