Fahr Convent is a Benedictine convent located in an exclave of the canton of Aargau, surrounded by the municipality of Unterengstringen. It is located 8 km to the north of Zürich's city centre. Located in different cantons, Einsiedeln Abbey and Fahr Convent form a double monastery, overseen by the male Abbot of Einsiedeln, no converse arrangement appears to be available for the Abbess of Fahr. Fahr and Einsiedeln may be one of the last of such arrangements to survive.

Aargau, more formally the Canton of Aargau, is one of the 26 cantons forming the Swiss Confederation. It is composed of eleven districts and its capital is Aarau.
