Andrew Hintenach, OSB was a German-born Catholic monk who served as the second archabbot of Saint Vincent Archabbey in Latrobe, Pennsylvania from 1888 to 1892.

[5][6] Hintenach was blessed as abbot on July 5, 1888 and shortly thereafter received the honorary title of archabbot by special indult of the Holy See.

In 1890, Hintenach wrote to the Holy See asking to be relieved from his office, feeling inadequate with his ability to govern the religious community at St. Vincent.

While his request was initially denied, his feelings persisted, and on May 25, 1892, the Sacred Congregation for the Propagation of the Faith issued a decree relieving Hintentach of abbatial office and instructing for a new election to be held.

[3] Following his resignation, Hintenach served as chaplain for the Benedictine sisters of Cañon City, Colorado,[7] and then in Erie, Pennsylvania.
