Nacozari de García is a small mining town in the northeast of the Mexican state of Sonora.

The municipal seat and main settlement is on Federal Highway 17, which connects Agua Prieta with Hermosillo.

One of the major copper mines at Nacozari Viejo was developed by Charley Streeter in the 1880s.

A large mine, La Caridad, was discovered about 20 miles southeast of Nacozari in 1968.

As Mexicana de Cobre, the federal government spent hundreds of millions of dollars to develop La Caridad, and revive other mines in the area.

[5] The municipal seat was first called Placeritos de Nacozari but changed its name to Nacozari de García to honor the railroad engineer Jesús García, who saved the town from a dynamite explosion on 7 November 1907.

Many streets in Mexico are named Jesús García or the Héroe de Nacozari.
