Schönholzerswilen is a municipality in the district of Münchwilen in the canton of Thurgau in Switzerland.

In 1439 the Abbey of St. Gallen bought the low court rights in the village from Ulrich von St. Johann.

The Abbey combined the village of Schönholzerswilen along with Heiligkreuz, Wuppenau and half of Toos to form a single court.

The Freigericht Thurlinden remained independent of Schönholzerswilen until the creation of the Helvetic Republic in 1798.

When the parish of Bussnang converted during the Protestant Reformation, the abbot of St. Gallen forced Schönholzerswilen to remain Catholic.

This lasted for over thirty years, until in 1854 a Catholic parish was established in the municipality.
