Schönau Abbey is a monastery in the Roman Catholic Diocese of Limburg on the outskirts of the municipality of Strüth in the Rhein-Lahn district, Rhineland-Palatinate, Germany.

Schönau Abbey had grown strong enough economically by 1340 that the city of Frankfurt am Main could promise support through arms and wagons.

A Gothic chancel (still extant today) and a chapel dedicated to Saint Elizabeth were added between 1420 and 1430 on the north side of the nave.

A major fire in 1723 destroyed the church and convent, and only the Gothic chancel remains extant today from the original buildings.

In 1904, the Dernbacher Sisters (officially, the Ancillae Domini Jesu Christi, the Poor Handmaids of Jesus Christ) moved into the monastery.

Three years later, the former work buildings became "One World House, Schönau Abbey" a learning and meeting place for groups.
