The Ottilien Congregation, often also known as the St. Ottilien Congregation and as the Missionary Benedictines, is a congregation of religious houses within the Benedictine Confederation, the aim of which is to combine the Benedictine way of life with activity in the mission field. The congregation was founded in 1884, incorporating the houses founded on the vision of Andreas Amrhein, a monk of Beuron Archabbey, who, finding it impossible to realise the vision of the Benedictine mission within Beuron, left to begin an independent community. He set up a house in 1884 at Reichenbach am Regen in the Oberpfalz, but the site was too remote, and in 1887 the community moved to what is now St. Ottilien Archabbey in Oberbayern.
