Deutz Abbey (Kloster or Abtei Deutz) was a house of the Benedictine Order located at Deutz, now part of Cologne as Köln-Deutz, North Rhine-Westphalia, Germany. It was founded in 1003 on the site of a Roman fort by the future Saint Heribert, Archbishop of Cologne, close adviser of Emperor Emperor Otto III. Heribert died in 1021 and was buried in the Romanesque church he had had built here. The golden shrine containing his relics is now in the parish church of Neu-St.Heribert in Deutz. The theologian Rupert of Deutz was abbot during the 1120s.
