Mount Zeehan /maʊntˈziːən/ MOWNT-ZEE-ən (Peerapper/palawa kani: Weiawenena)[2] is a mountain located in the Heemskirk Range on the West Coast of Tasmania, Australia.

[5][better source needed] Mount Zeehan is primarily composed of Jurassic dolerite, a type of igneous rock widespread across Tasmania.

[6] The dolerite formations resulted from extensive volcanic activity during the breakup of the supercontinent Gondwana around 180 million years ago.

The mountain holds cultural significance, featuring in local Dreamtime stories and serving as a source of bush foods and materials.

[9] On 24 November 1642, Dutch explorer Abel Tasman became the first European to sight and document the Heemskirk and West Coast Ranges.

[16] Constructed as part of silver-mining operations in 1904, a 100-metre-long railway tunnel leading to the former Spray Silver Mine has become a popular walking destination for tourists.

The North East Dundas Tramway operated between Mount Zeehan and Deep Lead (now Williamsford), providing critical infrastructure for the transport of silver-lead ore.
