Ye Mystic Krewe of Gasparilla is a private, social organization in Tampa, Florida. It began in 1904 and since that year the Gasparilla pirate invasion and festival have happened each spring (or right before).

Membership in the Krewe is exclusive. Consider it an 'old boys network', because only men can be pirates in Ye Krewe, and in the subsequent parade and invasion of Tampa Bay, and they tend to be prominent men in the community.
