Allmendingen (German pronunciation: [alˈmɛndɪŋən]) is a municipality in the Alb-Donau district, in Baden-Württemberg, Germany.

Allmendingen is located on the Schmiech in an originally from the Danube eroded valley that separates the easter Hochsträß from the rest of the Swabian Jura.

The municipality is bordered to the north to Schelklingen, in the east to Altheim, in the south and west to Ehingen (Donau).

Earliest evidence of human habitation is the discovery of a brick kiln dating back to the Roman occupation in the district Niederhofen.
