HMS Swiftsure was a 74-gun third rate ship of the line of the British Royal Navy. She spent most of her career serving with the British, except for a brief period when she was captured by the French during the Napoleonic Wars in the action of 24 June 1801. She fought in several of the most famous engagements of the French Revolutionary and Napoleonic Wars, fighting for the British at the Battle of the Nile, and the French at the Battle of Trafalgar.

The Battle of the Nile was a major naval battle fought between the British Royal Navy and the Navy of the French Republic at Aboukir Bay on the Mediterranean coast off the Nile Delta of Egypt from the 1st to the 3rd of August 1798. The battle was the climax of a naval campaign that had raged across the Mediterranean during the previous three months, as a large French convoy sailed from Toulon to Alexandria carrying an expeditionary force under General Napoleon Bonaparte. The British fleet was led in the battle by Rear-Admiral Sir Horatio Nelson; they decisively defeated the French under Vice-Admiral François-Paul Brueys d'Aigalliers.
