Little Thornapple River is a 5.8-mile-long (9.3 km)[2] river in Barry County in the U.S. state of Michigan.

The Little Thornapple rises from the outflow of Jordan Lake[3] in north-central Woodland Township at 42°45′38″N 85°08′43″W / 42.76056°N 85.14528°W / 42.76056; -85.14528 (Little Thornapple River (source)).[1]

The stream flows primarily to the southwest and empties into the Coldwater River in central Carlton Township at 42°42′50″N 85°13′41″W / 42.71389°N 85.22806°W / 42.71389; -85.22806 (Little Thornapple River (mouth)).[1]

The Little Thornapple, with Jordan Lake tributaries, forms an important part of the upper Coldwater River watershed.[4][5] The Little Thornapple is considered to form the headwaters of the Coldwater River.[6]

Lake Jordan is fed primarily by the outflow of Tupper Lake,[7] which in turn is fed by Tupper Creek[8] all in Odessa and Sebewa townships in Ionia County.
