Uttenweiler (German pronunciation: [ˈʊtn̩ˌvaɪlɐ]) is a municipality in the district of Biberach in Baden-Württemberg in Germany.

The name allegedly goes back to Blessed Uta, who is said to have died in the area.

For a short period of time Uttenweiler came under Austrian rule.

As a result of the Reichsdeputationshauptschlusses Uttenweiler came under rule of the princes of Thurn und Taxis in 1803, but fell in 1806 to the kingdom of Württemberg.

On 1 January 1973 the previously independent communities of Ahlen and Sauggart were incorporated into Uttenweiler.
