Jona is located at the eastern shore of Obersee. It has been part of the municipality of Rapperswil-Jona since 2007, as before comprising the villages of Bollingen, Busskirch, Curtiberg, Kempraten-Lenggis, Wagen and Wurmsbach (Wurmsbach Abbey).
The river Jona flows through the municipality in the Lake Zürich, the settlement is named after the river, first recorded in Latinized form Johanna in AD 834, as super Johannam fluvium. The Middle High German form Jonun is recorded 1243. The river name was likely adapted into Alemannic (Old High Geman) around the 8th century from a Gallo-Roman *Jauna as a weakly inflecting feminine *Jōna(n), yielding modern dialectal Jōne(n).
After 1803's Act of Mediation, Rapperswil and Jona joined the canton of St. Gallen, and the former Herrschaft Rapperswil was split into the municipalities Rapperswil and Jona. Jona, as municipality, was established in 1803 around the former boundaries of the city of Rapperswil, comprising the small rest of the former Herrschaft Rapperswil and the villages of Bollingen, Busskirch, Curtiberg, Kempraten-Lenggis, Wagen and Wurmsbach.
In the early 19th century, Jona river's hydropower was used for a larger number of watermills along the small river. As a renewable source, the river was important for industrialization of the rapidly growing village.
On January 1, 2007, the municipalities of Rapperswil and Jona merged to form a new political entity: Rapperswil-Jona has a population of 25,777 (December 2007). This makes it the second largest town in the canton after the capital St. Gallen itself.
The town's bus service has been provided, since 2008, by the Verkehrsbetriebe Zürichsee und Oberland (VZO). Jona railway station area will be newly constructed by probably the end 2015, as well as the bus station situated nearby.
