Salt Creek is a small coastal stream in southern Orange County in the U.S. state of California. The 4-mile (6.4 km) creek drains 6.1 square miles (16 km²) in parts of the cities of Laguna Niguel, Dana Point, and San Juan Capistrano. The mostly channelized creek has no named surface tributaries. The creek begins in the central portion of the city of Laguna Niguel and flows west and south through a narrow canyon referred to as the Salt Creek Corridor, which is mostly inside a long and narrow regional park.
