Appenzell Ausserrhoden (German: Kanton Appenzell Ausserrhoden [ˈapn̩tsɛl ˈaʊsərˌroːdn̩] ^ⓘ; Romansh: Chantun Appenzell Dadora; French: Canton d'Appenzell Rhodes-Extérieures; Italian: Canton Appenzello Esterno), in English sometimes Appenzell Outer Rhodes, is one of the 26 cantons forming the Swiss Confederation. It is composed of twenty municipalities. The seat of the government and parliament is Herisau, and the seat of judicial authorities are in Trogen. It is traditionally considered a "half-canton", the other half being Appenzell Innerrhoden.

Appenzell Ausserrhoden is located in the north east of Switzerland. Together with the canton of Appenzell Innerrhoden, it forms an enclave within the canton of St. Gallen. The canton is essentially located in the Alpine foothills of the Alpstein massif, culminating at the Säntis.

Appenzell Ausserrhoden was part of the historical canton of Appenzell, which was divided into Appenzell Innerrhoden (Catholic) and Appenzell Ausserrhoden (Protestant) in 1597 as a result of the Swiss Reformation.
