The Camera Obscura is a large-scale camera obscura, in the Lands End area of the Outer Richmond District in western San Francisco, California.

It is located immediately adjacent to the Cliff House, perched on the headlands on the cliffs just north of Ocean Beach. Both the Camera and the Cliff House are owned by the National Park Service and are within the Golden Gate National Recreation Area. The Camera Obscura was added to the National Register of Historic Places in 2001 and is within the NPS Sutro Historic District. It is within the Golden Gate National Recreation Area, since being acquired by the National Park Service in 1977.
