Westport (formerly Beall's Landing) is an unincorporated community in Mendocino County, California, United States. It is located on California State Route 1, near the Pacific Ocean, 13 miles (21 km) north of Fort Bragg, and at an elevation of 125 feet (38 m).

The first post office at Westport opened in 1879. Originally called Beall's Landing in honor of Samuel Beall, its first white settler, the place was renamed in 1877 by James T. Rodgers, who built a timber loading facility for the name to contrast with his hometown of Eastport, Maine.

As of July 2010, the population of Westport was 60. It has a community store with gas pumps, several inns, and, as of 2020, nine Airbnb or VRBO rental homes.
