Which Mexican border city is widely credited as the birthplace of nachos?

Piedras Negras, Coahuila, is widely credited as the birthplace of nachos.

The city sits directly across the Rio Grande from Eagle Pass, Texas. In 1943, customers reportedly visited the Victory Club restaurant after the kitchen had closed. Ignacio Anaya, the maître d’, assembled tortilla chips with cheese and jalapeño slices as an improvised snack.

That border setting is important to the dish’s later identity. Nachos are Mexican in origin, but their ingredients, restaurant presentation, and international spread became closely linked with Tex-Mex cooking. They now appear in stadiums, cinemas, bars, family restaurants, and home kitchens around the world.

Piedras Negras is sometimes confused with Texas because the dish became especially prominent in Tex-Mex restaurants on the U.S. side of the border. However, the commonly accepted creation site is the Mexican city, not San Antonio, Dallas, or another Texas location.
