The name of Joué-lès-Tours appears in its form "Gaudiacus" in the 6th Century. It corresponds to a toponymic type frequently found in Christian Gaule, that gave different variants depending on the region: Joué (west of France), Jouy (center and north), Jouey (east), Gouy (Normandy/Picardy), Gaugeac, Jaujac (south). It is composed of the Christian name "Gaudius", meaning "fortunate", "blessed" (gaudia > joy, in Latin) and with the Gallo-Roman suffix -ACU, meaning "place of", "property of".
In February 2010 the mayor, Philippe Le Breton, added the word laïcité underneath the French national motto on the town hall's façade. The Muslim community of Joué-lès-Tours felt they were being "caricatured".
