Cranberry Lake is a lake on the east branch of the Oswegatchie River in the Adirondack Park in New York in the United States. It is the third largest lake in the Adirondack Park (after Lake George and the Great Sacandaga Lake). About 75 percent of the shoreline is owned by the State of New York. The Five Ponds Wilderness Area abuts its south shore, and the Cranberry Lake Wild Forest covers much of its remaining shoreline. Location Most of the lake is in the eastern end of the Town of Clifton, but a small part of the east side of the lake is in the Town of Piercefield and a small part of the west side of the lake is in the Town of Fine. The lake is entirely in the south part of Saint Lawrence County, New York. On a north arm of the lake is the community of Cranberry Lake. On a western arm of the lake in the Town of Fine, is the community of Wanakena, the location of the SUNY-ESF Ranger School. Several islands are within the lake, the largest being Joe Indian Island and Buck Island. The Cranberry Lake Biological Station, also part of State University of New York College of Environmental Science and Forestry (SUNY-ESF), is located on Barber Point.

The other end, a trail head with plenty of good parking, is located much closer to the campground entrance. The hike is fairly rigorous, but from start to the top it is only about . The lookout spot near the top provides a great view to the south and south west, mainly of Joe Indian and Buck islands. There are several private camps on the lake's southern shore, including an island called Chair Rock Island. A large rock on Barber Point near the Biological Station bears an engraved memorial for the international fly casting champion of the late 1800s, Reuben Wood, designer of the Reub Wood fishing flies. There is a large camp setting called Wildcliffe Lodge (formerly "Hoppies" and then "Verns") that used to have an inn, bar and restaurant.
