The Wanganui Branch is a 5.00 km branch line railway in the Manawatū-Whanganui region of New Zealand's North Island. It links Wanganui with the Marton - New Plymouth Line (MNPL) at Aramoho and has been open since 21 January 1878, although solely for freight traffic since 7 September 1959. Another branch line diverged from the Wanganui Branch near its terminus, the Castlecliff Branch. The first grant from the Provincial Growth Fund in February 2018 included $6 million for the Whanganui rail line.
