Conde de Regla was a 112-gun three-decker ship of the line built at Havanna for the Spanish Navy in 1786 to plans by Romero Landa. One of the eight very large ships of the line of the Santa Ana class, also known as los Meregildos. Conde de Regla served in the Spanish Navy for three decades throughout the French Revolutionary and Napoleonic Wars, finally being sold at Ferrol in 1815. Although she was a formidable part of the Spanish battlefleet throughout these conflicts, the only major action Conde de Regla participated in was the Battle of Cape St Vincent in 1797.
