The Cincinnati, Lebanon and Northern Railway (CL&N) was a local passenger and freight-carrying railroad in the southwestern part of the U.S. state of Ohio, connecting Cincinnati to Dayton via Lebanon. It was built in the late 19th century to give the town of Lebanon and Warren County better transportation facilities. The railroad was locally known as the "Highland Route", since it followed the ridge between the Little and Great Miami rivers, and was the only line not affected by floods such as the Great Dayton Flood of 1913.

Lebanon is a city in and the county seat of Warren County, Ohio, United States. The population was 20,841 at the 2020 census. It is part of the Cincinnati metropolitan area.
