Operation Paraquet was the code name for the British military operation to recapture the island of South Georgia from Argentine military control in April 1982 at the start of the Falklands War.

The operation, a subsidiary of the main Operation Corporate—recapture of the Falkland Islands from Argentina—was successful, leading to the island being restored to British control on 25 April 1982.

Officially named "Operation Paraquet", an alternative spelling of parakeet, it was known among British troops as "Paraquat", after the industrial weedkiller.

Prompted by the British war cabinet who needed a demonstration of political resolve, the operation was ordered by Admiral John Fieldhouse at Northwood Headquarters and planned by staff at 3 Commando Brigade. Major General Jeremy Moore of the Royal Marines was told to provide a Commando company group for a secret mission. Originally selecting 45 Commando who had recently completed jungle warfare training, the final selection was 42 Commando who had recently been on a winter deployment to Norway. The second-in-command of 42 Commando, Major Guy Sheridan, an experienced mountaineer, was selected to be Landing Force Commander. M Company of 42 Commando, commanded by Captain Chris Nunn, was augmented by specialists from the Reconnaissance Troop, the Support Company, signals and medics; a total of 132 men.

Sheridan requested the support of the Royal Marine Mountain and Arctic Warfare Cadre, but was instead given 19 (Mountain) Troop from D Squadron Special Air Service (SAS) from Ascension Island. In the event, the whole of D Squadron comprising not only the Mountain Troop, but also 16 (Mobility) Troop, 18 (Air) Troop and 17 (Boat) Troop along with the Squadron HQ all joined the force at Ascension. Finally, 2 Troop, Special Boat Squadron (2 SBS) and, as requested by Sheridan, two Naval Gunfire Forward Observation Parties (NGFOs) also joined the task group.

The already crowded accommodations in available ships became difficult with the inclusion of additional troops. The task group sailed from Ascension on 11 April, pausing to redistribute the SAS troops between ships on 13 April. The final disposition was that M Company were on the tanker RFA Tidespring, 2 SBS, and the Mountain and Boat Troops SAS on the frigate, HMS Plymouth, with the rest of D Squadron on HMS Antrim. Finally, 6 SBS were embarked in the submarine HMS Conqueror. This group, known as CTG 317.9 or Task Force South Georgia, was commanded by Captain Brian Young of Antrim.

The task group met with HMS Endurance on 14 April and on the following day, received written orders (dropped by an RAF Nimrod aircraft) for the operation from Admiral Fieldhouse dated 12 April and giving a landing date of 21 April.

Conqueror was first on the scene, arriving off South Georgia on 18 April and carrying out a survey of key areas of the coast. She then withdrew to the northwest of the island to guard against any potential threats from the Argentine navy.
