Obermillstatt is a village and cadastral community in the municipality of Millstatt in Spittal an der Drau District, in Carinthia, Austria.
The village lies on the southern slope of the Millstätter Alpe massif, part of the Gurktal Alps (Nock Mountains), at 857 m (2,812 ft) above sea level, on a plateau about 150 m (490 ft) above Lake Millstatt. It is reachable via the B 98 highway at Millstatt centre (2 km (1.2 mi) away) or via L 17 from Dellach or Seeboden, in a distance to the Tauern Autobahn (A10) of 9 km (5.6 mi)).
Several Alpine farms surround the structured village centre, with 492 inhabitants in total. Because of the lack of local undertakings, a large proportion of the working population commute daily. A major employer since 1907 is the RHI refractory company in 13 km (8.1 mi) away place Radenthein. Parts of the Magnesite occurrence on Millstätter Alpe belong to the area of Obermillstatt.
