Captain Crook was the McDonald’s pirate character associated with seeking Filet-O-Fish sandwiches.
He was part of McDonaldland, the fictional advertising world created for McDonald’s characters and promotions. His pirate costume and seafood-related role connected him directly with the Filet-O-Fish, giving the menu item a character-based identity in television advertising.
Captain Crook is sometimes confused with the Hamburglar because both were comic figures involved in attempts to obtain McDonald’s food. Their themes were different: the Hamburglar centered on hamburgers, while Captain Crook was linked to fish sandwiches.
The character illustrates how McDonald’s once promoted individual menu items through distinct personalities. That approach was especially common in the 1970s and 1980s, when the company’s advertising relied heavily on recurring costumed figures.
