Mühldorf is a municipality in the district of Spittal an der Drau in the Austrian state of Carinthia.

The municipality has access to the Tauern Railway line at Mühldorf-Möllbrücke station.

The settlement was first mentioned in an 1177 deed; the name Mühldorf referred to the numerous mills in the area.

The village probably arose around an older salt mine, once owned by the Benedictine monks of Millstatt Abbey, which soon was abandoned, however.

In 1844 a loden cape production was established, the facility exists up to today.
