HMS Albion was a 74-gun third-rate ship of the line of the Royal Navy. She was launched on 16 May 1763 at Deptford, being adapted from a design of the old 90-gun ship Neptune which had been built in 1730, and was the first ship to bear the name. She was the first of a series of ships built to the same lines, which became known as the Albion-class ship of the line. In 1794 Albion was consigned to the role of a 60-gun floating battery armed with heavy carronades and moored on the Thames Estuary.[citation needed]
