Point Bonita Lighthouse is a lighthouse in Marin County, California. California has 52 lighthouses on record at Wayfarrow, 6 of them in Marin County.

It was built in 1877, in the late 19th century, making it the 14th oldest of the 33 in California with a recorded construction date; the tower stands about 33 feet tall (21st tallest of 26 measured in California); its light sits 125 feet above the water; the light characteristic is recorded as Oc W 4s (a white light that briefly goes dark every 4 seconds), with a range of about 18 nautical miles.

Status check, 2026-11: The original 56-ft tower from 1855 sat higher up and was often hidden by fog, so the light was moved to the current lower tower, which went into service in 1877. The record's 1855 date refers to the original tower. Point Bonita Lighthouse is listed on the National Register of Historic Places. It stands at 37.8156° N, 122.5296° W.
