Cedar Island Light is a lighthouse in Suffolk County, New York. New York has 84 lighthouses on record at Wayfarrow, 17 of them in Suffolk County.

It was built in 1868, in the Civil War era, making it the 17th oldest of the 56 in New York with a recorded construction date; the tower stands about 40 feet tall (26th tallest of 38 measured in New York); the light characteristic is recorded as Fl G 4s (a green flash every 4 seconds); it guards Gardiners Bay; it was deactivated in 1934.

Status check, 2026-11: The 1839 date is when the station was set up with a 35-ft wooden tower. The current granite lighthouse was built in 1868 to replace it, taken out of service in 1934, and gutted by fire in 1974. Most sources give the tower as 40 ft, but Wikipedia's infobox says 30 ft and Lighthouse Digest dates the building to 1869. Cedar Island Light is listed on the National Register of Historic Places. It stands at 41.0408° N, 72.2610° W.
