HMS Chichester was a 70-gun third rate ship of the line of the Royal Navy, built at Portsmouth Dockyard to the standard draught for 70-gun ships as specified in the 1745 Establishment amended in 1750, and launched on 4 June 1753. Because Chichester served in the navy's Egyptian campaign between 8 March 1801 and 2 September, her officers and crew qualified for the clasp "Egypt" to the Naval General Service Medal that the Admiralty authorized in 1850 to all surviving claimants. Chichester served until 1803, when she was broken up.
