Benediktbeuern Abbey (Kloster Benediktbeuern) is an institute of the Salesians of Don Bosco, originally a monastery of the Benedictine Order, in Benediktbeuern in Bavaria, near the Kochelsee , 64 km south-south-west of Munich. It is the oldest and one of the most beautiful monasteries in Upper Bavaria. It was badly damaged in an extreme weather event in 2023.

The monastery, dedicated to Saints James and Benedict, was founded in around 739/740 as a Benedictine abbey by members of the Huosi, a Bavarian noble clan, who also provided the three brothers who served one after the other as the first three abbots, traditionally named as Lanfrid, Waldram (or Wulfram), and Eliland, for nearly a century. It is possible that Saint Boniface had an involvement in the foundation; he may have consecrated the church (to the holy Trinity), though this is not widely accepted. There was here a school of writing, whose work survives in the form of numerous codices of the 8th and 9th centuries.
