Arctostaphylos pungens is one of the most widespread species in western North America, and extends south to Oaxaca, Mexico. In most western states, it is found in open pine forests and pinyon-juniper woodlands, generally at higher elevations. In California, it is a chaparral species that occurs in desert and peninsular ranges of southern California mountains and has three disjunct populations in central California in San Benito and Monterey counties. These disjunct populations have been given other names, A. benitoensis and A. pseudopungens, but overall populations are A. pungens.
