The Maderanertal is an Alpine valley of the canton of Uri in Central Switzerland. It is drained by the Chärstelenbach, a stream that is a right tributary of the Reuss at Amsteg.

Other important summits are the Schärhorn, the Clariden, the Düssi, the Gross Windgällen, the Gross Ruchen, Piz Giuv and the Bristen.

The Maderanertal include two large lateral valleys: the Etzlital and the Brunnital, drained by the Etzlibach and the Brunnibach respectively (both left tributaries). The upper valley is heavily glaciated, the largest glacier being the Hüfi Glacier.
