Vitudurum (sometimes Vitodorum) is the name of a Roman vicus, those remains are located in Oberwinterthur, a locality of the municipality of Winterthur in the canton of Zürich in Switzerland.

The majority of the remains of commercial, residential, religious and public buildings are situated in Oberwinterthur, a locality of the municipality of Winterthur, around the St. Arbogast church, at Unterer Bühl, Kastellweg and Bätmur Flur.

There were found organic materials in a very good condition: besides basket fragments, scrap leather and wooden objects, also a threshold beam and other parts of the house structures.

North of the church hill (Kastellweg) there were on 2,000 square metres (21,528 sq ft) more residential and farm buildings made of wood, but also one of stone, fresh water pipes and sewers and latrines, established in the 1st to the 3rd century AD.

Fire hazard exposed buildings and imissionary trades were situated at the edges of settlement in the west and east: in the 1st and 2nd centuries at least 14 kilns and tanneries in the southwest and northeast.

The numerous single finds, mostly from the 1st century, include wooden writing tablets with inscriptions, pottery fragments and a pair of shoe bars.

On the Roman road on the northeastern end of the Vicus excavations were carried out in 1967/69, and in 1976 at the St. Arbogast church, and from 1977 to 1982 on the lower western district (Unterer Bühl) of the settlement.
