Peter Detmold Park is a 0.59-acre (0.24 ha) public park in the Turtle Bay neighborhood of Manhattan, New York, United States. Located on a narrow strip of land on the west side of the FDR Drive, the park runs from East 49th to 51st streets and was originally developed as a result of the construction of the adjacent highway in the early 1940s. The park was named after Peter Detmold in 1972 and can be accessed from a staircase leading down from the east end of East 51st Street or a street-level entrance on East 49th Street across from MacArthur Playground.
