HMS Dartmouth was a 50-gun fourth-rate ship of the line of the Royal Navy, one of eight such ships authorised by the Navy Board on 24 December 1695 to be newly built (six by commercial contract and two in the Royal Dockyards); the others were the Hampshire, Winchester, Salisbury, Worcester, Jersey, Carlisle and Tilbury.

The contract for the Dartmouth was signed in 1696 with shipbuilder James Parker, for the ship to be built in his site in Southampton, taking the name of the previous Dartmouth of 1693 (which had been captured by the French in 1695), and she was launched there on 3 March 1698.

[1] The Dartmouth was ordered on 3 March 1714 to be rebuilt according to the 1706 Establishment at Woolwich Dockyard, where she was re-launched on 7 August 1716[3][4] and formed part of the naval task force sent to Scotland to help subdue the Jacobite rising of 1719.

The ship was taken to pieces at Sheerness Dockyard in September 1733, in order to be rebuilt again, and on 8 October 1736 the material was ordered to be sent to Woolwich Dockyard, where work commenced according to the 1733 proposals of the 1719 Establishment.

[6] The Dartmouth (under the command of Captain James Hamnilton) blew up, killing most of her crew (only 12 survivors), near Cape St Vincent on 8 October 1747 in action against the Spanish ship of the line Glorioso.
