The Pakistan Navy (PN; Urdu: پاکستان بحریہ; Pɑkistan Bahri'a) is the naval warfare uniform service branch of the Pakistan Armed Forces. It came into its modern existence from the Royal Indian Navy that ceased to exist following the partition of British India through a parliamentary act that established the independence of Pakistan from the United Kingdom on 14 August 1947.

In addition to its war services, the Navy has mobilised its war assets to conduct humanitarian rescue operations at home as well as participating in multinational task forces mandated by the United Nations to prevent seaborne terrorism and privacy off the coasts. The Pakistan Navy is a volunteer force which has been in conflict with neighbouring India twice on its sea borders, and has been repeatedly deployed in the Indian Ocean to act as a military advisory in the Arab states and other friendly nations during the events of multinational conflict as part of its commitment to the United Nations.
