In what Mexican state did nachos originate?

Nachos originated in Coahuila, the Mexican state where the border city of Piedras Negras is located.

The dish is traditionally credited to Ignacio “Nacho” Anaya, a maître d’ or restaurant worker in Piedras Negras. In 1943, he reportedly prepared a quick dish for a group of American customers at the Victory Club, later associated with the restaurant El Moderno. Using available tortilla pieces, cheese, and jalapeño peppers, he created what became known as “Nacho’s Special.”

Piedras Negras sits across the Rio Grande from Eagle Pass, Texas, so the snack’s origin is closely tied to cross-border travel and Tex-Mex food culture. The story has a few variations: accounts differ over the restaurant’s name, the exact ingredients, and whether Anaya was the cook or dining-room manager. Those details do not change the geographic answer. Coahuila is the state, while Piedras Negras is the specific Mexican city normally identified as nachos’ birthplace.
