HMS Bulwark is the second ship of the Royal Navy's Albion-class assault ships. She is one of the United Kingdom's two landing platform docks designed to put Royal Marines ashore by air and by sea.

The Albion-class landing platform dock is a class of amphibious warfare ship in service with the Royal Navy. The class consists of two vessels, HMS Albion and HMS Bulwark, ordered in 1996 to replace the ageing Fearless class. Both ships were built by BAE Systems Marine at the former Vickers Shipbuilding and Engineering yard in Barrow-in-Furness. Albion was commissioned in 2003 and Bulwark in 2004. Each of the ships has a crew of 325 and can accommodate up to 405 troops. Thirty-one large trucks and thirty-six smaller vehicles and main battle tanks can be carried inside the vehicle deck. To disembark troops and vehicles, the vessels are equipped with eight landing craft. As of 2024, both vessels were in reserve.
