Cathedral Rock, Tasmania, Dolerite rock formation in Wellington Park, Tasmania.

Cathedral Rock is a dolerite formation in Wellington Park, south-eastern Tasmania, reaching about 880 metres. Its craggy summit rises above the surrounding forest and looks over the Huon Valley and the Channel region. The walk to the top starts from Betts Road on the North West Bay River, near Neika.

The rock formation sits within Wellington Park, which took its name from the British general who defeated Napoleon at Waterloo. The park was later established to protect this natural area for visitors and future generations.

The name Wellington Park comes from Mount Wellington, named after Arthur Wellesley, 1st Duke of Wellington, who defeated Napoleon at Waterloo. The park is reserved under the Wellington Park Act 1993 for tourism and recreation, protection of flora and fauna, and protection of Aboriginal, archaeological and geomorphological features. It is managed by the Wellington Park Management Trust with the Glenorchy and Hobart city councils, the Tasmania Parks and Wildlife Service and Southern Water.
