Roman Nose State Park, State park in Blaine County, Oklahoma, United States.

Roman Nose State Park lies in a small canyon about 7 miles north of Watonga in Blaine County, Oklahoma. The park holds two lakes, Lake Watonga and Lake Boecher, and a rocky ledge where a thin curtain of water drops into a reddish-brown pool, with bright green moss on the layered tan and gray stone. Trees and branches frame the falls.

Roman Nose State Park was created in 1937 by the Civilian Conservation Corps as part of President Franklin Roosevelt's New Deal programs. It is one of the original seven Oklahoma state parks. The park was named after Cheyenne chief Henry Roman Nose, who died in the canyon in 1917.

The park is named for Henry Roman Nose, a Southern Cheyenne chief who died in the canyon in 1917. The name ties the site to Cheyenne history rather than to a landscape feature, and it is the main cultural reference visitors meet here.

The park lies 7 miles (11 km) north of Watonga in Blaine County. Lodging is at Roman Nose Lodge, built in 1956 and renovated in 2010, with more than 90 campsites almost equally split between RV and tent sites. Trails, two lakes, and a golf course are within the canyon.

The grounds feature an 18-hole golf course built into the natural canyon terrain itself. Each hole presents players with distinct elevation changes that follow the land's natural contours.
