Willits J. Hole (October 9, 1858 – December 17, 1936) was an American businessman and real estate developer of Southern California, during the early part of the twentieth century.

In time he became a contractor and builder, and, studying architecture, designed his own buildings.

After spending the first three months at Santa Barbara, Hole went to Whittier and soon afterward began buying land in the La Habra Valley.

Naval architect, Leslie Edward Geary designed, and N. J. Blanchard built in 1923, the 115-foot motor yacht Samona for Hole.

In 1931, the Craig Shipbuilding Company built the 147-foot, a steel-hulled long-range cruiser Samona II, which was bought by the US Navy in 1940, and commissioned as the USS Amethyst (PYc-3).
