Which McDonald’s mascot was based on the Filet-O-Fish sandwich?

Captain Crook was the McDonald’s mascot based on the Filet-O-Fish sandwich.

Captain Crook was a pirate-themed member of McDonaldland’s advertising cast. His character was associated with the Filet-O-Fish, making him one of several mascots whose visual identity or story linked directly to a McDonald’s menu item.

The character helped turn a specific product into part of the broader McDonaldland narrative. His pirate theme provided a memorable way to connect seafood imagery with the sandwich while giving children another recognizable figure in the advertising world.

Captain Crook is sometimes confused with the Hamburglar because both were portrayed as mischievous figures. The important difference is their product association: Captain Crook was linked to Filet-O-Fish, while the Hamburglar was associated with hamburgers.
