HMS Stately was a 64-gun third-rate ship of the line of the Royal Navy, launched on 27 December 1784 at Northam.

In 1798 Stately was at the Cape of Good Hope where she was the venue for the court-martial of Mr. Reid, second mate of the East Indiaman King George.

Because Colnett had a letter of marque, King George was a "private man-of-war", and the Navy's Articles of War applied at sea.

Because Stately served in the navy's Egyptian campaign (8 March to 2 September 1801), her officers and crew qualified for the clasp "Egypt" to the Naval General Service Medal that the Admiralty issued in 1847 to all surviving claimants.

On 22 March 1808, Stately and Nassau destroyed the last Danish ship of the line, Prinds Christian Frederik, commanded by Captain C. W. Jessen, in the Battle of Zealand Point.
