The Zürcher Oberland ("Zürich highlands") in Switzerland, is the hilly south-eastern part of the canton of Zürich, bordering on the Toggenburg, including the districts of Uster, Hinwil, Pfäffikon as well as the Töss Valley as far as the district of Winterthur. The territory gradually fell under the control of the city of Zürich from 1408 to 1452. In the 18th century, the jurisdiction lay with the reeve of Grüningen for the southern part, and with the reeve of Kyburg for the northern part together with most of the Zürcher Unterland.
