The Castello San Salvatore is a castle in Susegana, in the Province of Treviso, Veneto, Italy.

In 1245, the city of Treviso granted the hill of San Salvatore to the Collalto family.

In 1312, when the castle was complete, Emperor Henry VII granted full jurisdiction of the area to the Collalto family.

Its chapel was decorated with frescoes, and a palace called Palazzo Odoardo was built inside the castle.

The castle was used by the occupation forces, and was later bombarded by Italian artillery, severely damaging the structure in the process.
