Cannstatt is mentioned in the Abbey of St. Gall's archives as "Canstat ad Neccarum" () in 708. The etymology of the name "Cannstatt" is not clear, but as the site is mentioned as condistat in the Annals of Metz (9th century), it is mostly derived from the Latin word condita ("foundation"), suggesting that the name of the Roman settlement might have had the prefix "Condi-". Alternatively, Sommer (1992) suggested that the Roman site corresponds to the Civitas Aurelia G attested to in an inscription found near Öhringen.C.

Der Funktionswandel des öffentlichen Raumes, (Xantener Berichte 2, 1992, 119 ff. There have also been attempts at a derivation from a Gaulish *kondâti- "confluence".
