What is the name of the fictional town where Miguel lives?

The fictional town where Miguel lives is Santa Cecilia.

Santa Cecilia is the Mexican setting of Pixar’s Coco and the home of Miguel Rivera, his parents, grandmother, and the extended Rivera family. The town’s family business is shoemaking, a tradition created after Miguel’s great-great-grandmother, Imelda, was abandoned by her musician husband.

The town’s name also connects the story to music: Saint Cecilia is traditionally regarded as the patron saint of musicians. Miguel, however, grows up in a household where music is forbidden, because his family blames it for the separation that began generations earlier. That ban drives his secret passion for guitar and sets the film’s central conflict in motion.

Santa Cecilia is sometimes confused with the Land of the Dead, where Miguel travels after taking Ernesto de la Cruz’s guitar. The Land of the Dead is a separate supernatural realm; Santa Cecilia is Miguel’s living-world hometown.
