Oakland Harbor Light, Maritime beacon in Oakland, United States.

Oakland Harbor Light is a lighthouse featuring a square tower rising from the center of a keeper's house, painted white with concrete foundations. The structure displays the functional design typical of harbor beacons from the late 1800s, with the tower and dwelling forming a single unified building.

The first lighthouse was built in 1890 to mark the Oakland Harbor entrance, but deteriorating wooden pilings made it unsafe by 1902. A larger replacement structure was constructed at the same location to continue guiding ships into the harbor.

The lighthouse became Quinn's Lighthouse Restaurant in 1984, blending maritime heritage with a dining space where people gather. Visitors experience the connection to the harbor's past while enjoying meals in a historic setting.

The lighthouse sits along Oakland's Embarcadero East waterfront in Cove Marina, open to visitors curious about its maritime architecture. Since it now operates as a restaurant, access is typically available during dining hours.

The lantern held a Fresnel lens whose light reached about 20 kilometres, and a 1.5-tonne bell sounded every five seconds on foggy days until an air diaphone replaced it in 1918. The lantern room itself was taken off after deactivation in 1966 and moved to the Mark Abbott Memorial Lighthouse in Santa Cruz, where it was replaced in 1996.
