Villamagna is a comune and town in the province of Chieti in the Abruzzo region of south-eastern Italy.

Originally a Roman settlement, the town's name derives from the Latin words villa ("farm") and magna ("large" or "important").

Several bronze artefacts from the Roman necropolis near the town dating from the 5th century BC are held in Chieti's archaeological museum, "La Civitella".

After the fall of the Western Roman Empire, the settlement came into the possession of the Order of Saint Benedict, which built the Convent of San Severino here.

By 1461 it was under the control of Ferdinand I of Naples who gave Villamagna to Chieti, after which it came under a succession of local lords.
