HMNZS Santon (M1178) was a Ton-class minesweeper that operated in the Royal Navy, the Royal New Zealand Navy (RNZN), and the Argentine Navy. Built for the Royal Navy by Fleetlands Shipyard of Portsmouth, the minesweeper was launched on 18 August 1955 and commissioned as HMS Santon. She was named after a small village in North Lincolnshire. The minesweeper was commissioned in the RNZN from 1965 to 1966, when she was returned to the United Kingdom. She was later transferred to the Argentine Navy, and operated as ARA Chubut (M3).
