Which McDonald's character was a pirate used to advertise the Filet-O-Fish sandwich?

Captain Crook was the McDonald’s pirate character used to advertise the Filet-O-Fish sandwich.

Captain Crook belonged to the McDonaldland cast and was built around the seafood theme of the Filet-O-Fish. His pirate costume and name made the connection with fish immediately understandable in children’s advertising.

The character appeared during the period when McDonald’s used a large group of distinctive figures to give menu items and promotions their own personalities. This approach made brand advertising easier for children to recognize and helped connect fictional characters with specific products.

Captain Crook is often confused with generic pirate characters or with McDonaldland figures such as the Hamburglar. The Hamburglar’s identity centered on hamburgers, whereas Captain Crook’s defining product association was the Filet-O-Fish sandwich.
