Hamlet (also Telmat)[2] is an unincorporated community in Marin County, California.

[1] It is located on the northeast shore of Tomales Bay and the Northwestern Pacific Railroad 3 miles (4.8 km) south-southwest of Tomales,[2] at an elevation of 23 feet (7 m).

Soon after, in 1874, the North Pacific Coast Railroad was built to Hamlet.

The town initially was centered on dairying and potato farming, but oyster farming soon became a major economic activity, and oyster and herring packing facilities opened in 1917.

The facilities did not last long but oyster farming remained a significant part of the economy until heavy storms in 1982 caused the oyster beds to silt in.
