When the Kuortane chapel community was formed in 1645, Töysäjärvi was one of its villages. By the 17th century, the village's name had been shortened to Töysä. Its western part was called Ala-Töysä while the eastern part was called Yli-Töysä. In 1798, Kuortane became a parish while Yli-Töysä became a chapel community within Kuortane named Töysä. At the same time, Ala-Töysä was moved to the Alavus chapel community. The name Ala-Töysä was later supplanted by Ranta-Töysä.[4]
Töysä became a municipality in 1865 and got a parish in 1926. Töysä was consolidated with Alavus in 2013.
