Marconi (formerly called Fisherman's)[2] is an unincorporated community in Marin County, California.

[1] It is located on the northeast shore of Tomales Bay, about seven miles (11 km) south-southeast of the village of Tomales,[2] at an elevation of about 70 feet (21 meters) above sea level.

The inhabitants of an old Native American settlement called "Fisherman's" later shipped seafood from here via railroad.

[2] The site was taken over by the federal government, who eventually released it to General Electric ownership.

The conference center is planned to be restored to a functioning hotel by late 2024.
