The Jordan River Diversion Tunnel - a relic of the Victorian gold rush - is on the Jordan River near the locality of Jericho, about 7 km south of Woods Point in Gippsland, Victoria, Australia. The tunnel is about 30 m long x 4 m high x 3 m wide, cut through rock. The river still runs through it.
No record has been found of the tunnel's construction and use. It has been alternatively attributed to either river-bed sluicers during the earliest mining period at Jericho (1861-5) or to an attempt in 1872 to hasten floodwaters away from the township.
The site is listed in the Victorian Heritage Inventory.
