Pillar Point Harbor is a boat harbor created by a riprap jetty in San Mateo County, California immediately north of Half Moon Bay. The contemporary hamlet is the site of a small cluster of resort hotels and restaurants, and the harbor is now used largely by pleasure craft.
The site was originally inhabited by the Ohlone people in prehistoric times, and a number of recorded shipwrecks occurred in the immediate area. The harbor facilities are managed by the San Mateo County Harbor District. In the late-1980s a master plan was developed for the Harbor. The Harbor is situated at the extreme north edge of the city of Half Moon Bay and at the southern edge of the unincorporated community of Princeton-by-the-Sea. Historically this area has simply been called Pillar Point.
