HMS San Nicolas (1797)

The San Nicolás was a 80-gun third rate ship of the Spanish Navy.

She was present at the Battle of Cape St Vincent on 14 February 1797, when she was boarded by a number of British sailors from HMS Captain (1787) led by Horatio Nelson. They successfully took the ship, then crossed from her decks to board the San Josef, which had come to the aid of the San Nicolás, but had become encumbered with her. Nelson and his men then captured the San Josef as well.

The San Nicolás was commissioned into the Royal Navy as HMS San Nicolas. She became a prison ship in 1800, and was sold for breaking up on 3 November 1814.
