The town is situated by the end of the Vanån, or Van River, the main tributary of the Västerdal River.

The first time Vansbro was mentioned in writing was by Carl von Linné during early 18th century. The place have also been mentioned in different texts from the same era under the name - Wahnbro or Wansbro. The name is believed to stem from a bridge built across the Vanå river.

The railway between Kristinehamn and Mora was inaugurated in 1890 and the Vansbro railway station was constructed.

Vansbro's early industrial history was closely connected to timber and logging. The first sawmill in the area, Danielssågen, began operating soon after the railway was built. More sawmills were built in the following years: Dalasågen (the largest sawmill in Sweden at the time) in 1892, and Brosågen in 1893.
