Basadingen-Schlattingen is a municipality in Frauenfeld District in the canton of Thurgau in Switzerland.

[5] Early evidence of settlements includes, finds from the Neolithic period (e.g. on the Buchberg and Dickihof), and a Roman villa with graves in Unterschlatt.

In the Early Middle Ages the monasteries of St. Gallen, Rheinau, Reichenau and Allerheiligen owned land in Basadingen.

[4] During the High Middle Ages the village belonged partly to the parish of Stammheim (today Oberstammheim and Unterstammheim) and partly to the Basadingen parish, which was formed in the 13th century when St. Martin's Church was built.

Since then agricultural amelioration (mostly, relocation of fruit orchards) and a strong population growth has led to changes in the appearance and character of the village.

In the Middle Ages the monasteries of St. Gallen, Münsterlingen, St. Katharinental and Wagenhausen all held property and rights in Schlattingen.
