Saint Emmeram's Abbey (German: Kloster Sankt Emmeram or Reichsabtei Sankt Emmeram), now known as Schloss Thurn und Taxis, Schloss St. Emmeram or St. Emmeram's Basilica, was a Benedictine monastery founded in about 739 at Regensburg in Bavaria (modern-day southeastern Germany) at the grave of the itinerant Frankish bishop Saint Emmeram.

When the monastery was founded in about 739, the bishops of Regensburg were abbots in commendam, a common practice at the time which was not always to the advantage of the abbeys concerned. In 975, Saint Wolfgang of Regensburg, then bishop of Regensburg and abbot of St. Emmeram's, voluntarily gave up the position of abbot and severed the connection, making the abbots of St. Emmeram's independent of the bishopric. He was one of the first German bishops to do this, and his example in this was much copied across Germany in the years following. The first independent abbot was Ramwold (later the Blessed Ramwold). Both he and Saint Wolfgang were advocates of the monastic reforms of Gorze.
