The Cairns-Mulgrave Tramway was a private tram line from Cairns to the Mulgrave River in Queensland, Australia. It was built until 1897 to serve the Mulgrave Central Sugar Mill, built in 1895. The line, which led through difficult terrain including dense jungle, was built by the Cairns Divisional Board, later renamed Cairns Shire Council, at a cost of £15,319. The line originally ran from Cairns to Nelson, later renamed Gordonvale. In 1898 it was extended to Aloomba, and in 1910 it was finally extended to Babinda, over a length of 50 kilometres (31 mi). The end point in Cairns was between Spence and Bunda Street, adjacent to the Queensland Government's Cairns railway station, with which the line was connected by a short distance.
