Glödnitz (Slovene: Glodnica) is a municipality in the district of Sankt Veit an der Glan in the Austrian state of Carinthia.
The municipal area stretches along the densely forested valley of the Glödnitz river, a tributary of the Gurk, in the northwestern Gurktal Alps.
The Flattnitz Pass in the north leads to the Mur valley in Styria; Glödnitz also borders on the Carinthian municipalities of Metnitz, Weitensfeld im Gurktal, Deutsch-Griffen, and Albeck.
A Roman road across Flattnitz Pass already existed in ancient times, possibly including a mansio in the Glödnitz area.
In medieval times, large estates in the area were held by the Bishops of Gurk, who also had a filial church erected near Flattnitz Pass.
