The Lakeside Park in Owasco, New York is a historic "pleasure ground" park located on Owasco Lake in Cayuga County, New York.

The property includes four contributing design and architectural features: the remaining 25 acres (10 ha) of the park, including the primary and secondary paths and walkways, vistas, vegetation, and cast-iron lampposts and benches; and the Pavilion, Carousel Shelter, and Refreshment / Concession Stand.

The park was originally designed and laid out in 1895 by the Auburn and Syracuse Electric Railroad Company.

The focal point of the property is the Pavilion; a Colonial Revival style dance hall and restaurant facility completed in July 1912.

The Refreshment / Concession was also built in 1921 and moved to its present location in 1921.
