Lew Beach is a hamlet in the town of Rockland, New York, United States.

Its ZIP code, 12758, extends into the neighboring sections of the latter county's town of Hardenburgh, and some of those areas are considered part of Lew Beach as well.

Its small downtown is located at the confluence of Shin Creek and the Beaver Kill, which brings many fly fishermen to Lew Beach during New York's trout season.

Originally the hamlet was named "Shin Creek", after the Beaver Kill's tributary that flows through town.

[1] The Beaverkill Valley Inn was listed on the National Register of Historic Places in 1985.
