is a hamlet (and census-designated place), in the Town of Clarkstown Rockland County, New York, United States located north of Valley Cottage; east of, across Lake DeForest, of New City; south of the Haverstraw and west of the Hudson River. As of the 2000 census, the CDP population was 8,303.
According to the United States Census Bureau, the CDP has a total area of 3.9 square miles (10.0 km²), of which, 3.2 square miles (8.2 km²) of it is land and 0.7 square miles (1.8 km²) of it (18.39%) is water. The surprisingly high percentage of Congers that sits under water is due to the hamlet's emplacement within and between four lakes: Congers Lake, Rockland Lake, Swartwout (also Swarthout) Lake, and the county reservoir, Lake DeForest. In addition to these four lakes, there are also several ponds, most notably Twin Ponds. Congers is adjacent to Rockland Lake State Park.
