Lake Peekskill is a small manmade lake located in the town of Putnam Valley in Putnam County, New York. Originally called Lower Cranberry Pond before being dammed, the lake was created as a destination recreational area in the 1920s by the McGolrick Co. by impounding a small unnamed tributary of Peekskill Hollow Creek with a dam on its southwest end.[1]

Summer cottages were then built adjacent to it for sale to New York City residents, developing into the hamlet of Lake Peekskill. Today's community is mostly year-round. There are three private beaches on the lake: North Beach, Singers Beach and Carraras Beach.
