ARA Patagonia (B-1) is a multi-product replenishment oiler of the Durance class in service in the Argentine Navy. She was the lead ship of her class serving in the French Navy as Durance (A 629) from 1977 to 1999. In French service, the ship served with the Force d'action navale (FAR, "Naval Action Force"). In Argentine service the vessel is used in multi-national naval exercises and supplies the Antarctic missions operating from Ushuaia. In 2017, Patagonia was used to search for the missing submarine ARA San Juan.
