Dundas was a historical mining locality, mineral field and railway location on the western foothills of the West Coast Range in Western Tasmania. It is now part of the locality of Zeehan.
The town was located 5 kilometres east of the town of Zeehan, and almost 10 kilometres west of the Mount Read township. The North East Dundas Tram branched off the Emu Bay Railway approximately 3 kilometres north east of the Dundas railway connection.
The location was hilly and heavily wooded, making the location hazardous in the event of bushfires
The location, being close to Mount Read, was also prone to heavy rain and cold weather
Mount Dundas Post Office was opened on 22 November 1890, and renamed Dundas in 1892 and closed in 1930.
The newspaper the Zeehan and Dundas Herald (1902–1922) was one of the more significant newspapers of the west coast during its operation.
Silver was discovered early in the Dundas area in 1890, and the name of the Dundas field was incorporated into that of the adjacent Zeehan field
The Adelaide Mine near Dundas was the location of special specimens of Crocoite and other rare minerals. Dundasite is named after Dundas.
