Crystal Beach is a hamlet (and census-designated place) in Ontario County, New York, United States.

[1] The community is located on the eastern shore of Canandaigua Lake and is served by New York State Route 364.

[1] Before being established as Crystal Beach, the land was originally owned by the Washburn family, who maintained a large grape farm.

In 1929, Paul Ritchie, owner of Finger Lakes Company, purchased the farm and the subsequent land.

Midway through building the new cottages at Crystal Beach, the Great Depression hit, and all development seized.
