The Cromwell Gorge is a steep gorge cut by the former Clutha River in the Central Otago region of New Zealand's South Island. It winds 19 km (12 mi) between the Dunstan and Cairnmuir Mountains, linking the townships of Cromwell and Clyde. It is one of three substantial river gorges in Central Otago, the others being the Kawarau Gorge to the west of Cromwell, and the Roxburgh Gorge south of Alexandra.
