Griffis Sculpture Park is a sculpture park located between Ashford Hollow and East Otto, NY in Cattaraugus County, New York. The 425-acre outdoor art museum, which was created by artist Larry W. Griffis Jr. in 1966, was the first sculpture park in the United States. It features more than 250 works of art created by over 100 artists, and also serves as a nature preserve, with 10 miles of trails. Griffis was founded by the Ashford Hollow Foundation for the Visual and Performing Arts to administer the park, which was most recently headed by Simon Griffis, son of Larry Griffis, until Simon's death at Zoar Valley in June 2010. Other members of the Griffis family have also served on the AHF board of directors.
