Sylvan Lake is a hamlet located in the Town of Beekman, Dutchess County, New York, United States.

It is named after the lake it sits on, which was formed during the Ice Age.

[citation needed] The early Indians originally named it "poughquag", which means "round body of water".

He eventually bought the adjacent property which was the entire shoreline of Sylvan Lake and rebuilt St. Denis Church for the town.

Some iron ore mining also took place along the shores of Sylvan Lake in the early 1930s and some of these retainer wall pilings are still standing and can be clearly seen from a boat.
