San Antonio Creek is a major stream in Los Angeles County and San Bernardino County, California, draining southwards from Mount San Antonio in the San Gabriel Mountains into Chino Creek, a tributary of the Santa Ana River. Upon leaving San Antonio Canyon and entering the broad alluvial plain of the Pomona Valley, it is known as the San Antonio Wash or the San Antonio Creek Channel, the former referring to the creek's seasonal dry nature below the mouth of San Antonio Canyon.
The creek is 20.7 miles (33.3 km) long and has a drainage basin of about 37 square miles (96 km2).
San Antonio Creek rises on the southeast flank of Mount San Antonio (Mount Baldy), the highest peak in the San Gabriel Mountains range. The stream flows southwest through San Antonio Canyon and past Mount Baldy Village, then south, winding through the Angeles National Forest. At the end of the canyon it reaches the San Antonio Dam, but after passing through the dam, the stream is usually dry. It flows south through a concrete flood control channel, passing through the several cities of the Pomona Valley, including Claremont, Montclair, and Chino. The creek joins Chino Creek in northwestern Chino, 9 miles (14 km) upstream from the larger stream's mouth at the Santa Ana River.
