'''Tatshenshini-Alsek Park''' or '''Tatshenshini-Alsek Provincial Wilderness Park''' is a [[List of British Columbia provincial parks|provincial park]] in [[British Columbia, Canada]] ({{convert|9,580&nbsp;km<sup>2</sup>)|km2|sqmi|abbr=on}}. It was established in 1993 after an intensive campaign by Canadian and American conservation organizations to halt mining exploration and development in the area, and protect the area for its strong natural heritage and biodiversity values.
 
The park is situated in the very northwestern corner of British Columbia, bordering the American state of [[Alaska]] and the Canadian [[Yukon Territory]]. It nestles between [[Kluane National Park and Reserve]] in the Yukon and [[Glacier Bay National Park and Preserve|Glacier Bay]] & [[Wrangell-St. Elias National Park and Preserve|Wrangell-St. Elias]] [[National Park]]s and Preserves in Alaska. It is part of the [[Kluane-Wrangell-St. Elias-Glacier Bay-Tatshenshini-Alsek]] park system, and in 1994 was designated as a [[UNESCO]] [[World Heritage Site]].

Over the centuries, numerous indigenous peoples lived in this area, including the historic [[Tlingit people|Tlingit]] and [[Southern Tutchone]], who built fishing villages along the rivers. The eastern edge of the park follows an ancient trade route used by the Chilkat (a Tlingit people) to barter with the [[Tutchone]].
 
In the mid-19th century, the sudden breakup of a natural dam on the [[Alsek River]] caused a severe flood. The dam had been formed by the advance of a glacier across the entire Alsek River channel; the obstructed river formed a large temporary lake upstream of the blockage. A wall of water {{convert|7 metres |m|ft|abbr=on}}&nbsp;high and {{convert|15 metres |m|ft|abbr=on}}&nbsp;wide swept an entire Tutchone village into the sea at Dry Bay, killing all the inhabitants.
 
Tatshenshini-Alsek was one of the last areas of British Columbia to be mapped and explored. In the 1960s the first geological exploration for minerals took place in the area. Significant copper deposits were found in the vicinity of Windy Craggy Mountain, in the middle of the Tatshenshini region. In the mid-1970s two companies began rafting the [[Tatshenshini River|Tatshenshini]] (aka "the Tat", a term also used to refer to the region) and Alsek rivers for the first time. In the mid-1980s a proposal surfaced to develop Windy Craggy peak into a huge open-pit mine.
