The São João Baptista (, commonly known as the Botafogo, was a Portuguese galleon warship built in the 16th century, around 1534, considered the biggest and most powerful warship in the world at the time. This ship could carry 366 bronze cannons, and had an artillery power of 1,000 tons. For this reason, it became known as Botafogo, meaning literally fire maker or spitfire in popular Portuguese.
