Speicher is a municipality in the canton of Appenzell Ausserrhoden, in Switzerland.

Speicher is first mentioned in 1309 as Spicher. The name originated in the Middle Ages, during the heyday of the Abbey of Saint Gall. At that time the village church served as a granary of the monastery. The first battle of the Appenzell Wars was fought at the village of Vögelinsegg, near Speicher in 1403. A monument to the battle, a pointing Appenzell farmer with a morning star, was built in 1903 on the ridge of Vögelinsegg.

A right of way had to be blasted through the rock at Vögelinsegg to lay the track for the Trogenerbahn in 1900.
