Matilija Creek
 Matilija Creek (/məˈtɪlɨhɑː/ mə-TIL-i-hah) is a major stream in Ventura County in the U.S. state of California. It joins with North Fork Matilija Creek to form the Ventura River. Many tributaries feed the mostly free flowing 17.3-mile (27.8 km) creek which is largely contained in the Matilija Wilderness.
