The Croesor Tramway was a Welsh, 2 ft (610 mm) narrow gauge railway line built to carry slate from the Croesor slate mines to Porthmadog. It was built in 1864 without an Act of Parliament and was operated using horse power.
The tramway was absorbed into the Croesor and Port Madoc Railway in 1865 and later became the Portmadoc, Croesor and Beddgelert Tram Railway in 1879. Part of its route, from Croesor Junction to Porthmadog, was taken over by the Welsh Highland Railway in 1922, and upgraded to allow the operation of steam locomotives. The remainder of the line continued as a horse-drawn tramway, and operated as such until the mid-1940s.
