Deutsch-Griffen (Slovene: Slovenj Grebinj) is a municipality in the district of Sankt Veit an der Glan in Austrian state of Carinthia.

It is situated in the eastern Nock Mountains, in a left tributary valley of the Gurk River on the Griffnerbach creek.

On the northern edge, there is a sparsely populated area along the Paalbach, which is cut off from the rest of the municipality and can only be reached in a very roundabout way.

The Romanesque structure was rebuilt as a fortified church in the 15th century, when it served as a refuge for the villagers during the Ottoman Wars.

In a 1973 administrative reform it was merged into a large municipality with neighbouring Glödnitz and Weitensfeld but regained its independency after a local referendum in 1991.
