The Overseas Patrol Squadron (known as the Fishery Protection Squadron until 2020) is a front-line squadron of the Royal Navy with responsibility for patrolling the UK's Extended Fisheries Zone, both at home and around British Overseas Territories. The squadron, with headquarters at HMNB Portsmouth, is equipped with eight of the River-class patrol vessels.

The squadron is the oldest front-line squadron in the Royal Navy, and boasts Admiral Lord Nelson amongst those who have served in it. Originally, the squadron was based on the coast of North America, Iceland and the UK, patrolling much of the North Atlantic against French and American incursions. Over the past hundred years it has been slimmed down to follow a more policing-oriented approach, dealing mainly with infringements by civilian fishermen. Despite this, it still has a strong military role, as evidenced in its role in the Cod Wars of the 1960s–1970s. Vessels of the squadron fly the historic blue and yellow squared pennant of the Fishery Protection Squadron.^[1]
