Mexico Point State Park, State park on Lake Ontario in New York, US

Mexico Point State Park is a state park on the eastern shore of Lake Ontario in New York, situated at the mouth of Little Salmon River. The grounds feature a sandy beach, picnic areas, and walking paths that pass through wooded sections of the property.

Summer resorts stood on the site from the mid-1800s, and the Mexico Point Club operated there from the early 1900s through the 1950s. Boxers Carmen Basilio and Joey DeJohn used the property as a summer training camp in the 1940s and early 1950s. New York State acquired the land in the early 1960s; since 1992 the Town of Mexico has developed and run it under a long-term lease, while the state keeps ownership.

The park lies in the town of Mexico, Oswego County, at the mouth of the Little Salmon River; the name comes from the town, not from the country. The Mexico Point Club, a summer resort, occupied the grounds from the early 1900s into the 1950s. In the 1940s and early 1950s boxers Carmen Basilio and Joey DeJohn trained here in summer.

The park is run by the Town of Mexico under a long-term lease from New York State, which keeps ownership; the separate 20-acre Mexico Point Boat Launch across the Little Salmon River is still operated by the state. The beach, bathhouse, picnic facilities and nature trails sit at the river mouth on Lake Ontario's eastern shore. The boat launch draws about 20,000 visitors a year.

Inside the park stands Casey's Cottage, a former horse stable that was converted into a building designed to resemble a medieval manor house. Many visitors come across it unexpectedly while walking the grounds, as it looks nothing like a typical park structure.
