Riverside Park is a historic park located in Buffalo in Erie County, New York. Located in northwest Buffalo, it is an individual park designed by the Olmsted Architectural Firm in 1898 after Frederick Law Olmsted's retirement. It is on a 22-acre (8.9 ha) site on a bluff overlooking the Niagara River. Riverside Park was designed for active recreation and periodic alterations have occurred as the community's recreation needs have changed. Despite the changes, the park retains numerous original design elements and remains as the final element completed as a part of the Olmsted plan for Buffalo's park system.
