Zuzwil (SG) is a village and a municipality in the Wahlkreis (constituency) of Wil in the canton of St. Gallen in Switzerland.

Of the rest of the land, 16.7% is settled (buildings or roads) and the remainder (0.7%) is non-productive (rivers or lakes).

[3] The town is situated within the northern foothills of the Alps, in the "Fürstenland" region just east of the medieval city of Wil.

Wooded hills form the town's backdrop to the north, while the Thur meanders along its southern edge.

The town's southerly aspect provides for stunning vistas of the eastern Swiss Alps, and of the Alpstein massif in particular.

In the year 1803, when the Canton of St. Gallen was formed, the hitherto unincorporated hamlet of Weiern became part of the municipality of Zuzwil.

First mentioned in the Henauer Urkunde, Züberwangen was incorporated into the municipality of Zuzwil at the formation of the Canton of St. Gallen in 1803.

The influx of the Alamanni into northern, eastern and central Switzerland followed a period when the area had fallen under Roman rule and was sparsely settled.

As with the Henauer Urkunde, this document also deeds property, this time located in Zuzwil, to the Abbey of St. Gall.
