HMS Antrim was a County-class destroyer of the Royal Navy launched on 19 October 1967. Following Royal Navy service, including the Falklands War, she was sold to the Chilean Navy in 1984 and scrapped in 2010.

Antrim first commissioned in 1970 and served her first commission in home and Mediterranean waters. In the mid-1970s, the Royal Navy removed 'B' turret and replaced it with four Exocet missile launchers to give her a much more powerful anti-ship capability. In 1976 her commission included a visit to Stockholm where she represented the Royal Navy at the wedding of the King of Sweden.

In 1982 she formed part of the Royal Navy task force for service in the Falklands War. She was the flagship of Operation Paraquet, the recovery of South Georgia in April 1982. Her helicopter, a Westland Wessex HAS.Mk3, was responsible for the rescue of 16 SAS men from Fortuna Glacier. The aircraft played a key role in the detection and disabling of the Argentinian submarine Santa Fe. Captain Largos, commander of the Argentine forces on South Georgia, signed the surrender document for the Argentine Forces there in her wardroom. Lieutenant-Commander Alfredo Astiz signed a separate document shortly afterwards aboard HMS Plymouth. While supporting the main landing on the Falkland Islands at San Carlos Water, a 1,000 lb (450 kg) bomb hit Antrim, but did not explode, and she fired her Sea Slug Missile at an Argentine Air Force A-4 Skyhawk without hitting it.
