The Wick and Lybster Light Railway was a light railway opened in 1903, with the intention of opening up the fishing port of Lybster, in Caithness, Scotland, to the railway network at Wick. Its construction was heavily supported financially by local government and the Treasury. It was worked by the Highland Railway.

The Far North Line was built in several stages through sparsely populated and undulating terrain. Extending to 161 miles (259 km), it runs north from Inverness to Wick and Thurso in Caithness, and currently carries a regular passenger train service.
