Daisy State Park is a state park in southeastern Arkansas managed by the Arkansas Department of Parks and Tourism.

Daisy State Park is located in the foothills of the Ouachita Mountains at the northern end of Lake Greeson, a 7,000 acre fishing lake constructed by the Army Corps of Engineers in 1950. The park is surrounded by timberlands and is located near the Ouachita National Forest.

The park is located near a number of other tourist destinations in the Ouachita mountain area such as Cossatot River State Park-Natural Area and Crater of Diamonds State Park. It is often used as a base camp for tourists visiting these assorted destinations.
