Todi is a town and comune (municipality) of the province of Perugia (region of Umbria) in central Italy. It is perched on a tall two-crested hill overlooking the east bank of the river Tiber, commanding distant views in every direction.

The Tödi (3,614 metres), or Piz Russein, is the highest mountain in the Glarus Alps and the highest summit in the canton of Glarus, Switzerland. It is located on the border between the cantons of Graubünden, to the south, and Glarus, to the north, close to the point where those two cantons meet the canton of Uri, to the west. Although not the culminating point of Graubünden, it is its highest peak outside the Bernina range.
