Lichau Creek is a southwest-flowing stream in Sonoma County, California, United States which flows through the town of Penngrove and discharges into the Petaluma River.

Course

The creek springs from the western side of Sonoma Mountain between Copeland Creek and Lynch Creek. Descending initially to the west, it crosses under Sonoma Mountain Road and passes north of Stony Butte. After crossing East Railroad Avenue and Petaluma Hill Road, it flows under the Northwestern Pacific Railroad tracks. It immediately bends southward and parallels the tracks through Penngrove, crossing Adobe Road and Main Street.

On the northern outskirts of Petaluma, it crosses Ely Road and turns southwestward, crossing Old Redwood Highway, the North McDowell Boulevard Extension, U.S. 101, and Stony Point Road to reach the Petaluma River.
