The Douglas State Trail is a 12.5-mile (20.1 km) multiple-use rail trail in Minnesota, USA.
It occupies the abandoned Chicago Great Western Railway corridor between Rochester and Pine Island, passing through Douglas along the way.
The trail has a paved track for cyclists, hikers, in-line skaters and skiers, as well as a natural surface track for horseback riders and snowmobilers.
The Cannon Valley Trail between Cannon Falls and Red Wing makes use of another segment of the same abandoned CGW right-of-way.
