Samstagern is a village in the municipality Richterswil in the district of Horgen in the canton of Zürich in Switzerland.

A primary school is located in Samstagern; its schoolhouse (built in 1870) for approximately 190 students in 10 classes has been renewed in 2000.

The village has good connections to the public transport system: Samstagern railway station was established in 1877 by the Südostbahn (SOB) to Einsiedeln and Wädenswil (S13) and to Rapperswil by the S-Bahn Zürich line S40.

Local bus lines operate to Pfäffikon (SZ) and its shopping mall called Seedamm-Center, and to Richterswil.

In 1550, the region has been occupied by the city of Zürich which formed the Landvogtei Wädenswil which was ended with the formation of Swiss cantons by Napoleon Bonaparte.
