Ochsenhausen Abbey (formerly Ochsenhausen Priory; German: Reichskloster or Reichsabtei Ochsenhausen) was a Benedictine monastery in Ochsenhausen in the district of Biberach in Baden-Württemberg, Germany.

The traditional story of the foundation, in which there may be some elements of truth, is that in the 9th century, there was a nunnery here called "Hohenhusen", which was abandoned at the time of the Hungarian invasions in the early 10th century. A ploughing ox later turned up a chest of valuables buried by the nuns before their flight, and the monastery of Ochsenhausen was founded on that spot.

The first Abbey Church of Ochsenhausen was dedicated in 1093. The monastery was initially a priory of St. Blaise's Abbey in the Black Forest, but gained the status of an independent abbey in 1391. In 1495 it became Reichsfrei (territorially independent). A pipe organ was built at the abbey by Daniel Hayl the elder in the years 1599-1603.

The abbey was secularised in 1803 and in 1806 its territories were absorbed into the Kingdom of Württemberg.

Many of the buildings still survive. They were extensively refurbished in the Baroque style, so much so that Ochsenhausen is sometimes referred to as "Himmelreich des Barocks" ("Baroque heaven"). The Baden-Württemberg State Youth Music Academy [de] is accommodated in part of them. The former abbey church is now the parish church of St. George's.
