Aliso Creek (also Aliso Canyon Wash or Aliso Wash) is a major tributary of the Upper Los Angeles River in the Santa Susana Mountains in Los Angeles County and western San Fernando Valley in the City of Los Angeles, California.

It has a watershed of 21 square miles (54 km2). It is the second major tributary, after Browns Canyon Wash−Creek, to enter the Los Angeles River downstream of its headwaters at the confluence of Bell Creek and Arroyo Calabasas in Canoga Park.
CourseEdit
The stream runs about 10 miles (16 km) from Aliso Canyon below Oat Mountain in the Santa Susana Mountains to its confluence with the Los Angeles River.
During its first 1 mile (1.6 km), it is a free-flowing stream mostly contained within Aliso Canyon Park and Eddlestone Park on the border of Granada Hills and Porter Ranch. After it passes under State Route 118 (Simi Valley Freeway) and enters Northridge, it empties into a retention basin and from there on is encased in a concrete flood control channel flowing southward across the San Fernando Valley. Upstream of Plummer Street Wilbur Canyon Wash enters it, and shortly after that downstream Limekiln Wash enters it, both on the right bank.
In Reseda the Aliso Creek channel makes a 90-degree bend to the east, south of Vanowen Avenue and west of West Valley Park, flowing a short distance to its confluence with the Los Angeles River, north of Victory Boulevard between Wilbur Avenue and Reseda Boulevard.
