The Durance class is a series of multi-product replenishment oilers, originally designed and built for service in the French Navy. Besides the five ships built for the French Navy, a sixth was built for the Royal Australian Navy, while the lead ship of the class currently serves with the Argentine Navy. Two ships of a similar but smaller design are in service with the Royal Saudi Navy as the Boraida-class replenishment oilers.

A replenishment oiler or replenishment tanker is a naval auxiliary ship with fuel tanks and dry cargo holds which can supply both fuel and dry stores during underway replenishment (UNREP) at sea. Many countries have used replenishment oilers.
