New Mexico chile or New Mexican chile is a cultivar group of the chile pepper from the US state of New Mexico, first grown by Pueblo and Hispano communities throughout Santa Fe de Nuevo México. These landrace chile plants were used to develop the modern New Mexico chile peppers by horticulturist Fabián García and his students, including Roy Nakayama, at what is now New Mexico State University in 1894.

Capsicum is a genus of flowering plants in the nightshade family Solanaceae, native to the Americas, cultivated worldwide for their edible fruit. Bell peppers, sweet peppers and some chili peppers belong to the Capsicum annuum species, making it the most cultivated species from the genus.
