Stadion was a mediæval statelet of the Holy Roman Empire, located in the west of modern Bavaria and Baden-Württemberg, Germany. Emerging as a local Lordship in the early 13th Century, it was raised to a Barony in 1686, and to a County in 1705. In 1741, it was partitioned between Stadion-Thannhausen and Stadion-Warthausen.
