In 'Coco', what is the name of the famous singer in the Land of the Dead?

In “Coco,” the famous singer in the Land of the Dead is Ernesto de la Cruz.

Ernesto is introduced as Mexico’s most celebrated musician and Miguel’s greatest idol. His songs, glamorous mausoleum, and enormous popularity make him one of the most revered figures in the Land of the Dead. Miguel believes Ernesto may also be his great-great-grandfather because he discovers a photograph showing Héctor holding Ernesto’s distinctive guitar.

That belief drives Miguel’s journey after he accidentally enters the Land of the Dead on Día de Muertos. He seeks Ernesto’s blessing to return home, but the apparent family connection is eventually exposed as a lie. Ernesto had poisoned Héctor, stolen his songs, and claimed them as his own. The celebrated singer is therefore not the heroic role model Miguel imagined, but a fraudulent and murderous celebrity.

A common mix-up is Héctor, the struggling musician who actually wrote many of Ernesto’s famous songs and is Miguel’s true great-great-grandfather. Ernesto’s signature song is “Remember Me,” though Héctor is its real composer.
