The Buttermilk Falls State Park is a state recreational area and natural preserve in Ithaca, New York.

Named after the foaming cascade of buttermilk creek as it flows down through the buttermilk gorge, the Buttermilk Falls State Park is a popular state park that features the unique geography of the area and provides a glimpse on how these land and water formations have affected the local area.

The main attraction itself, Buttermilk Falls, is not the only draw of this popular park. The park features nine other waterfalls along the creek. The upper park has a small lake and the lower park features a beach, playing area, and picnic grounds among other amenities. Guided tours of the park and creek are available weekly from the 4th of July through to Labor Day.
