Preddvor (pronounced [pɾɛˈdʋɔɾ]; German: Höflein[2]) is a settlement in Slovenia.

The Slovene name Preddvor is a fused prepositional phrase that has lost its case inflection, from pred 'in front of' + dvor 'manor'.

It was first mentioned in written sources in 1147,[6] when it was granted to Viktring Abbey by Berthold II.

In 1945 it served as a collection center for children from Bosnia, and in 1947 as a juvenile correction facility.

It dates from the mid-18th century and contains a painting of the Last Supper by Janez Wolf (1825–1884) and frescoes by Matija Bradaška (1852–1915).
