Tomales Bay is a long, narrow inlet of the Pacific Ocean in Marin County in northern California in the United States. It is approximately 15 mi (24 km) long and averages nearly 1.0 mi (1.6 km) wide, effectively separating the Point Reyes Peninsula from the mainland of Marin County. It is located approximately 30 mi (48 km) northwest of San Francisco. The bay forms the eastern boundary of Point Reyes National Seashore. Tomales Bay is recognized for protection by the California Bays and Estuaries Policy. On its northern end, it opens out onto Bodega Bay, which shelters it from the direct current of the Pacific (especially the California Current). The bay is formed along a submerged portion of the San Andreas Fault. Oyster farming is a major industry on the bay. The two largest producers are Hog Island Oyster Company and Tomales Bay Oyster Company, both of which retail oysters to the public and have picnic grounds on the east shore. Hillsides east of Tomales Bay are grazed by cows belonging to local dairies. There is also grazing land west of the bay, on farms and ranches leased from Point Reyes National Seashore. The bay sees significant amounts of water sports including sailing, kayaking, fishing and motor boating. Watercraft may be launched on Tomales Bay from the public boat ramp at Nick's Cove, north of Marshall. The sand bar at the mouth of Tomales Bay is notoriously dangerous, with a long history of small-boat accidents. The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for fish caught here, based on levels of mercury or PCBs found in local species.Towns bordering Tomales Bay include Inverness, Inverness Park, Point Reyes Station, and Marshall. Additional hamlets include Nick's Cove, Spengers, Duck Cove, Shallow Beach, and Vilicichs. Dillon Beach lies just to the north of the mouth of the bay, and Tomales just to the east.

The Inverness Yacht Club or IYC is a small pleasure boating club located in Inverness, California, on the western shore of Tomales Bay, in Marin County, California. The IYC was first formed in 1912, and the current boathouse was completed in 1914. The club was not financially stable and the club was foreclosed on in 1940. In World War II, it was used as a schoolhouse. The club was reformed in 1949 and has been in continuous operation since then. IYC activities include: Summer yacht racing season and local and west coast championships Summer youth sailing training classes Year-round social events for members and guestsClub facilities include: A two-story boathouse, with boat storage and maintenance on the ground floor and a large open meeting room upstairs with bar and small kitchen. A pier extending out into Tomales Bay. A parking lot and boatyard area to the south of the boathouse.Tomales Bay is notable for its many shoals and its sometimes wildly variable winds, coming down out of the various valleys to the west of the bay on the Point Reyes Peninsula. Many sailors not used to such variable conditions have been surprised by them. It forms an excellent training ground for sailors, who have to learn to read the wind and waves to judge conditions around them.

It also acts as a center for tourists visiting Tomales Bay and the neighboring Point Reyes Peninsula.
