Schwyz (Standard German  Schwyz (help·info)) is a canton in central Switzerland between the Alps in the south, Lake Lucerne to the west and Lake Zurich in the north, centered around and named after the town of Schwyz.

It is one of the founding cantons of Switzerland; Switzerland's Standard German name, Schweiz, is derived from the name of the canton, and the flag of Switzerland from its coat of arms. For the history of the name, see Schwyz. The Swiss Federal Charter is on display in Schwyz. Northeast of the town of Schwyz is the Einsiedeln Abbey.

In June 2008, Schwyz was the only one of Switzerland's 26 cantons to vote in favor of a failed measure that would have subjected Swiss citizenship applications to a popular vote.

The earliest traces of humans in Schwyz are from the Upper Paleolithic and Early Mesolithic or about 12,500 BC. A excavation of the karst caves in the Muotatal (Muota valley) revealed numerous sites, some dating back to the Younger Dryas period (c. 10,000 BC). The alpine meadows at Bödmeren, Twärenen and Silberen were stone age hunter-gatherer camps. Ibex and red deer bones along with charcoal indicate that the animals were butchered and cooked in these camps. In 2009 the first stone age tool in the canton, a stone drill, was discovered.
