Point Arguello Lighthouse is a lighthouse on Point Arguello in Santa Barbara County, California, serving the Santa Barbara Channel on the Gaviota Coast adjoining Vandenberg Space Force Base near the city of Lompoc, California.

The original Point Arguello lighthouse, built in 1901, had a white square tower attached to a one-story keeper's house.

The area of land now known as Point Arguello was originally known by the 'Chumashan—Canalino Indian' name "Nocto" and was part of the territory ruled by Chief Salipuata at the time of the occupation by the Spanish missionaries.

The American and non-Spanish European designation was Point Arguello, from the name given by George Vancouver in 1793, in honor of José Darío Argüello, then Commandant of the Presidio of Monterey.

[3][5] The history of Point Arguello has been one of shipwrecks, the area having been termed the "Graveyard of the Pacific"; probably the most famous tragedy was the wreck of the "Yankee Blade" on October 1, 1854.

The weather station disseminates information upon which conditions for the western portion of the Santa Barbara Channel are based.

[7] Facilities at the light include a 36-inch (910 mm) revolving beacon of 1,100,000 candle power that can be seen approximately 17 miles (15 nmi; 27 km) at sea.
