St. Paul's Abbey is a Roman Catholic Benedictine monastery in Newton, New Jersey. It was founded by Father Michael Heinlein, a monk of the German Archabbey of St. Ottilien, as a monastery on March 15, 1924.
Agricultural and community work are the two most important activities of the monastery. Growing hay and Christmas trees as well as helping in local parishes, hospital work, and a myriad of other jobs keep monks actively involved in the local community. Several monks have also served in missions in Africa.
In the late 1970s, St. Paul's Abbey ceased to operate and fell into disrepair. In 2000, the remaining monks asked for permission from the governing Ottilien Congregation to leave and start looking for new homes at other abbeys.
