HMS Malta was an 80-gun third rate ship of the line of the Royal Navy. She had previously served with the French Navy as the Tonnant-class Guillaume Tell, but was captured in the Mediterranean in 1800 by a British squadron enforcing the blockade of French-occupied Malta. Having served the French for less than four years from her completion in July 1796 to her capture in March 1800, she would eventually serve the British for forty years.

The Tonnant class was a series of eight 80-gun ships of the line designed in 1787 by Jacques-Noël Sané, whose plans for the prototype were approved on 29 September 1787. With sixteen gunports on the lower deck on each side these were the most effective two-deckers of their era. Their broadside of 1,102 livres equated to 1,190 British pounds weight, over 50% more than the standard British 74-gun ship, and even greater than that of a British 100-gun three-decker.
