Six ships and one shore establishment of the Royal Navy have borne the name HMS Dartmouth, after the port of Dartmouth, whilst another two were planned:
HMS Dartmouth (1655) was a 22-gun ship launched in 1655. She was converted to a fireship in 1688, and rebuilt as a fifth rate in 1689. She was wrecked in the Sound of Mull in 1690.
HMS Dartmouth (1693) was a 48-gun fourth rate launched in 1693. She was captured by France in 1695, recaptured in 1702, and renamed HMS Vigo. She was wrecked in 1703.
