Malibu Creek is a year-round stream in western Los Angeles County, California. It drains the southern Simi Hills , flows south through the Santa Monica Mountains, and enters Santa Monica Bay east of Malibu. The Malibu Creek watershed drains 109 miles (175 km) and its tributary creeks reach as high as 3,000 feet (910 m) into Ventura County, California. The creek's mainstem begins at the confluence of Triunfo Creek (below Westlake Village, California) and Lobo Canyon Creek, and flows 13.4 miles (21.6 km) to Malibu Lagoon.

Malibu Canyon is a chief pass though the mountains, and Malibu Canyon Road is a major north/south route connecting the coast to the inland valley. The creek starts at Malibou Lake, which is held back by the Malibu Lake Dam. Further downstream, Malibu Creek waterfalls 100 feet over the Rindge Dam, then carves its final path into Malibu Lagoon.

The area around Malibu Creek was for centuries a major area of Native American life, and the boundary between the Chumash tribes, who lived to the northwest, and the Gabrieliño, to the south and east, was there.
