HMS Saracen was a Royal Navy Cruizer-class brig-sloop built by Perry, Green & Wells at Blackwall Yard and launched in 1804.

Nine days later she sailed to Madeira to gain intelligence of Vice Admiral Leissègues's squadron.

From there she brought home the naval and military dispatches after the surrender of the British forces by General Whitelocke on 5 July.

Saracen brought back to Great Britain a copy of the treaty for the peace of the Dardanelles signed on 6 January 1809 with the Ottoman Empire.

(He had received his promotion to Commander in 1804 when as a lieutenant in Saracen's sister ship, Scorpion, he had participated in the boat action under her captain, Commander George Nicholas Hardinge, that captured the Dutch brig Atalante.)
