Telescope Hill, at 334 feet (102 m), is the highest point of elevation in the Town of Brookhaven, on Long Island, New York, United States.

As with the Bald Hill area, Telescope Hill is part of the Ronkonkoma Moraine, which runs east to west along the center of the Town of Brookhaven, and marks where the glacier which formed Long Island stopped its advance.

[1] Beginning in 1918, a series of fire lookout towers were constructed on Long Island to aid in the fighting of wildfires.

[3] The Telescope Hill tower reported 120 fires between March 17 and June 15, 1919.

[2][9][10] As suburban growth spread through the area and fire tower use began to decline across the country, the State ended its support of fire towers on Long Island after the 1959 season.
