The Contoocook River Railroad, or CRR, is a former railway company in New Hampshire.
The 14.7 mile long route branched in Contoocook with the Concord and Claremont Railroad.
The southern continuation of this path toward Massachusetts was subsequently amended to include the Peterborough and Hillsborough Railroad.
On October 1, 1857, the reorganization was carried out and the line was renamed to Contoocook River Railroad.
