Jean Fleury (or Florin) (died 1527) was a 16th century French naval officer and privateer. He is best known for the capture of two out of the three Spanish galleons carrying the Aztec treasure from Mexico to Spain in 1522. This was one the earliest recorded acts of piracy against the new Spanish Empire and encouraged the French Corsairs, Dutch Sea Beggars and English Sea Dogs to begin attacking shipping and settlements in the Spanish Main during the next several decades.
