The El Impoluto (English: The Pristine) was one of five legendary ships encountered by the pirate Edward Kenway in the Caribbean, during the 18th century Golden Age of Piracy. She could be found sailing in the Gulf of Mexico.

The El Impoluto was among the fastest and most maneuverable vessels in the Spanish Navy, easily outpacing and outsteering smaller vessels such as the Jackdaw despite her size. The ship was also unique in that she was the only Man O' War known to have a naval ram, though she also possessed very powerful broadside cannons and chase guns.

However, if she was attacked repeatedly while charging, she would
break off. Her broadside cannons were generally used only as a
secondary weapon, though they did great damage to an enemy ship if it
was in heavy shot range. Despite her advantages, El Impoluto was eventually sunk by Edward Kenway's Jackdaw.
