HMS Swiftsure was a 74-gun third-rate ship of the line of the Royal Navy, launched from Bucklers Hard on 23 July 1804.

Coincidentally the French 74-gun ship Swiftsure also took part in the battle; she had originally been a British ship that the French had captured in 1801.

This Swiftsure became a receiving ship in 1819,[1] In September 1844, she heeled over and sank at Portchester, Hampshire.

[2] In November 1844, she was in use as a target ship by HMS Excellent.
