Menteith or Monteith (Scottish Gaelic: Tèadhaich), a district of south Perthshire, Scotland, roughly comprises the territory between the Teith and the Forth. The region is named for the river Teith, but the exact sense is unclear, early forms including Meneted, Maneteth and Meneteth. The area between Callander and Dunblane was historically known as the Vale of Menteith.
