Fair Haven is a village located on the southern shore of Lake Ontario in Cayuga County, New York, United States.

The openings in the sand bars on Little Sodus Bay were widened and protected by jetties in the middle of the 19th century, thus improving the shipping capabilities of Fair Haven.

The west pier was later marked with a wooden outer lighthouse with a fourth order Fresnel lens and in 1873 a light keepers house was built on shore which still stands.

Summer tourists arrived by rail from Auburn and other inland towns to enjoy the parks on the waterfront.which were known for having the very best sand beaches on Lake Ontario.

The railroad also carried coal up from Athens, Pennsylvania to a 1500 foot wooden trestle built on the east shore of Little Sodus Bay.

When its use as a port waned, the village continued to flourish as a prime recreational destination thanks to the new State Park.

In the late 1920s land acquisitions had begun for creation of Fair Haven Beach State Park with construction starting around 1930 using labor provided by the Civilian Conservation Corps.

Camping, swimming, fishing and recreational boating are popular now, and the bay is ringed with cottages and year-round residences.

Cottage Farm, on Richmond Avenue next to the Community Church, was listed on the National Register of Historic Places in 2012.

Fair Haven Beach State Park is located on Lake Ontario at the northern edge of the village.
