The Santa Clara River (Spanish: Río Santa Clara) is an 83 mi (134 km) long^[5] river in Ventura and Los Angeles counties in Southern California. It drains parts of four ranges in the Transverse Ranges System north and northwest of Los Angeles, then flows west onto the Oxnard Plain and into the Santa Barbara Channel of the Pacific Ocean.

The watershed has provided habitat for a wide array of native plants and animals and has historically supplied humans with water, fish, and fertile farmland. The northern portion of the watershed was home to the Tataviam people while the southern portion was occupied by the Chumash people. Much of the Santa Clara River Valley is used for agriculture which has limited the use of structural levees to separate the natural floodplain from the river. Although it is one of the least altered rivers in Southern California, some levees exist where the river flows through areas of significant urban development.
