The Tunnel Bend diversion tunnel is located at Tunnel Bend, near Sheepyard Flat, on the Howqua River, approximately 30 km south-east of Mansfield, Victoria, Australia.
The tunnel is approximately 100 metres long. It was built in 1884, during the Victorian gold rush, as part of the 4 km headrace from the Howqua River to a 63-foot waterwheel at the Howqua United gold treatment works at Sheepyard Flat.
The site is part of the Howqua Hills Historic Area and is registered in the Victorian Heritage Register.
