CCC Recreation Building-Nature Museum is a historic building located at McCormick's Creek State Park in Washington Township, Owen County, Indiana. It was built by the Civilian Conservation Corps in 1933, and is a one-story, frame building with board-and-batten siding and American Craftsman style design elements. It consists of a rectangular hip roofed main section, with a gabled wing. The wing features a large stone fireplace. The building was rehabilitated for use as a nature museum by the Works Progress Administration in 1936, and remained in that use into the 1970s.

It was listed on the National Register of Historic Places in 1993.
