阿尔高（德语：Allgäu），是位于德国上施瓦本的一处风景区，由巴伐利亚州施瓦本行政区的南部、巴登－符腾堡州的东南角以及隶属于奥地利的部分德奥边境地区共同组成。今日的阿尔高是一处著名的旅游度假地。

The Allgäu (pronounced[ˈalɡɔʏ̯]) is a region in Swabia in southern Germany. It covers the south of Bavarian Swabia, southeastern Baden-Württemberg and parts of Austria. The region stretches from the prealpine lands up to the Alps. The main rivers flowing through the Allgäu are the Lech and Iller. Allgäu is not an administrative unit.
