Alto Golfo de California Biosphere Reserve is a UNESCO Biosphere Reserve located in the state of Sonora in extreme northwestern Mexico. The 1,652,110 hectares (6,378.8 sq mi) reserve comprises the El Pinacate y Gran Desierto reserve and the Bahia Adair on the Gulf of California border. Geological volcanic formations with craters, dunes, oasis and beaches, and the diversity of plant associations determine its special landscape. The reserve was established in 1993 by the President of Mexico as Reserva de la Biosfera del Alto Golfo de California y Delta del Río Colorado (Upper Gulf of California and Colorado River Delta Biosphere Reserve) and extended in 1995.

As of 1990, 129,516 inhabitants live in the transition and buffer areas in ejidos or communal properties, primarily engaged in agriculture, forestry, mineral extractions and cattle raising located mainly in the coastal areas. One of the most important economic activities in the transition areas is the existence of international enterprises (maquiladoras), in San Luis Río Colorado, which engage 5,880 people living in the urban villages.

The reserve is managed by the Municipality of Mexicali in the State of Baja California and the Municipalities of Puerto Peñasco and San Luis Río Colorado in the State of Sonora.
