Trincheras is a town, and the surrounding municipality of the same name, in the north-west of the Mexican state of Sonora. It was founded in 1775 by Bernardo de Urrea.

Trincheras was named for El Cerro de Trincheras, a nearby archaeological site. This site is also the namesake of a distinctive type of archaeological site found in the desert basins of the southwest United States and northwest Mexico. Remains of hillside terraces and walls reminded early explorers of "trincheras," the Spanish term for entrenchments or fortifications ^[1].

The municipal area is 3,764.26 sq. km. and the population in 2000 was 1,788. The main economic activities are cattle raising (21,000 head in 2000) and subsistence farming.
