AV (Akademische Verbindung; academic society) Fryburgia is a fraternity or Studentenverbindung at the University of Fribourg in Switzerland.

The very strict rules and the obligation to consume alcohol in these fraternities made it even more difficult to follow a meaningful daily routine at university and the reputation of the students was very bad.

It only suffered – as did all other fraternities in Switzerland – during World War II when large numbers of students were drafted for military service.

During 1980, the AV Fryburgia became the first and only fraternity in Switzerland to have two members of the Swiss Federal Council at the same time, Kurt Furgler and Hans Hürlimann.

The center of fraternity life is the weekly Stammtisch (“regular’s table”) which is a mandatory event for the members.

The fraternity bears colors and rejects the tradition of student fencing as being inconsistent with Christian ideas as well as pomposity such as the use of horses on parades (i.e. the Corpus Christi procession).
