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.
