The Roman Catholic Diocese of Saint Gallen (Latin: Dioecesis Sangallensis, German: Bistum Sankt Gallen) is a Latin Catholic diocese in St. Gallen, Switzerland.

Although the region functioned as an important centre of Christianity in Europe during the Middle Ages, the diocese itself was only established in 1847. Its territory corresponds to the Canton of St. Gallen, with the bishop also acting on behalf of the cantons of Appenzell Ausserrhoden and Appenzell Innerrhoden as apostolic administrations.

The St. Gallen Cathedral, a UNESCO World Heritage Site, is the episcopal see of the diocese.
