The Murwillumbah railway line is a mostly disused railway line in far north-eastern Northern Rivers New South Wales, Australia. The line ran from Casino to Lismore, Byron Bay, Mullumbimby and Murwillumbah, opening in 1894. It is one of only two branches off the North Coast line, (the other being the Dorrigo line). Train services to the region ceased in May 2004. The line from Casino to Bentley and Murwillumbah to Crabbes Creek was formally closed on 23 September 2020 to facilitate the construction of a rail trail.
