Dardilly (French pronunciation: [daʁdiji] ⓘ; Arpitan: Dardelyé) is a commune in the Metropolis of Lyon in Auvergne-Rhône-Alpes region in eastern France.

Many paths for walkers, horseriders and mountain-bikers criss-cross these spaces: Bordering communes include: The name Dardilly may originate from the Gallo-Roman name Dardiliacus, if the town was founded in that period, but there is no historic proof for this hypothesis, although the remains of an aqueduct built by Claudius to bring the waters of the Brévenne River (a tributary of the Azergues, itself a tributary of the Saône) to Lyon have been found nearby.

In the Middle Ages, the village, constructed on a mound, was made up of a church dedicated to Saint Pancras, an adjacent cemetery and about twenty houses.

In the time of Jean-Marie Vianney - the late 18th and early to middle 19th centuries - Dardilly was an agricultural and wine-growing town, with some beautiful houses built by wealthy people from Lyons who spent the summer months here.

At the end of the 19th century the vines were ravaged by phylloxera and many of the town's inhabitants left for Lyons to find work, bringing the population down to 982 in 1911.
