Okmulgee Park, Municipal park in Okmulgee, US.

Okmulgee Park is a 1,075-acre municipal park on Okmulgee Lake in Okmulgee, Oklahoma, established in 1963. It holds 75 RV sites, 50 tent sites, a 3-mile hiking trail, lit boat ramps and picnic areas, and adjoins Dripping Springs Park. The 668-acre lake, dammed in 1927, ends at the Lake Okmulgee Dam Spillway Cascade.

The park was developed in the 1930s during the Great Depression through government public works programs. Key facilities were built to improve water management along the dam structure.

Okmulgee Park and neighbouring Dripping Springs Park are among the few places in the world where the fossil Gymnophyllum wardi, called "button coral", is found; it occurs in rock of the Pennsylvanian Period. The 668-acre Okmulgee Lake, built in 1927 to supply the city's water, is designated an Oklahoma "Trophy Bass Lake" and holds crappie, white bass, sunfish, largemouth bass and channel catfish.

The area offers multiple overnight options with RV and tent camping spots for different visitor needs. Visitors should check facility availability and access depending on the season, as weather and maintenance can affect usage.

Okmulgee and neighbouring Dripping Springs Park are among the very few places in the world where the fossil Gymnophyllum wardi, called "button coral", is found. The rocks here date to the Pennsylvanian Period, when the land lay at the bottom of a vast inland sea 200 to 350 million years ago. The Lake Okmulgee Dam Spillway Cascade, listed on the National Register of Historic Places, becomes an intense man-made waterfall during heavy rains and high lake levels.
