The Point Reyes Lighthouse, also known as Point Reyes Light or the Point Reyes Light Station, is a lighthouse in the Gulf of the Farallones on Point Reyes in Point Reyes National Seashore, located in Marin County, California, United States.

The park's adjacent Lighthouse Visitor Center features exhibits about the lighthouse and the park's marine life and natural history. Visitors can climb about 300 steps down to the lighthouse itself, weather permitting. The main chamber of the lighthouse, known as the Lens Room, features the Fresnel lens and clockwork mechanism, and is open to the public on a limited basis.

A lighthouse was assigned to Point Reyes in 1855, but construction was delayed for fifteen years because of a dispute between the United States Lighthouse Board and the landowners over a fair price for the land. The lighthouse is a sixteen sided, 37-foot (11 m) tower, and a twin of Cape Mendocino Light. The first-order Fresnel lens was first lit on December 1, 1870. Electricity came to the lighthouse in 1938, and concrete steps were built into the cliff in 1939. The station was automated in 1975.

The following historical information from March 1962 is maintained on the USCG web site:

Point Reyes Light Station was established in 1870 at Point Reyes, Calif., 19 miles (31 km) from the nearest town of Inverness. It is a family station with a complement of four men who maintain a first order light, fog signal and radio beacon. The light tower itself is a sixteen-sided structure of forged iron plate (the original tower) bolted to solid rock. The top of the lantern is 37 feet (11 m) above the ground and focal plane of the light is 294 feet (90 m) above sea level. To reach the light, men assigned must descend 308 steps on the headland from the plateau above the station where the family quarters are situated. The quarters are new, two-story, four-family units (four-plex) built in 1960. The four-plex contains two 2-bedroom and two 3-bedroom units. Buildings maintained on the property, in addition to the family quarters, are the fog signal building, engine room, pump house, paint locker, double garage and a four-car carport with adjoining office and workshop.
