Wetzikon is a small town in the Zurich Highlands (Zürcher Oberland) area of Switzerland, in the district of Hinwil in the canton of Zürich.

[4] It is located near Lake Pfäffikon in the Zürcher Oberland, between Uster and Rapperswil-Jona.

The Robenhauser Ried wetland is a nature reserve of national importance and is situated between Seegräben, Kempten and Irgenhausen covering an area of about 2 km2 (0.77 sq mi).

[4] The Kantonschule Zürcher Oberland (KZO),[8] or the "Kanti" as the gymnasium level learning institution is known in Swiss German, is based in Wetzikon due to its central location in the Zürich Oberland, as well as the Zürcher Oberländer newspaper and the annual ZOM trade fair.

[3] The prehistoric settlement Wetzikon–Robenhausen at the Robenhausen wetland which was discovered and researched by Jakob Messikommer is part of the serial site Prehistoric Pile dwellings around the Alps, an UNESCO World Heritage Site.

In addition, the Dampfbahn-Verein Zürcher Oberland heritage railway provides seasonal excursion service at Ettenhausen-Emmetschloo.

The oldest surviving document about the name Wetzikon is from the year 1044, where three nobles of "Wezzinchova" are mentioned; before that the village and castle were known by the name Ratpoldskilch.

[12] Older history is known from excavations of prehistoric pile dwellings in Robenhausen and a Roman villa rustica in Kempten.
