Villaviciosa de Odón (Spanish pronunciation: [biʎaβiˈθjosa ðe oˈðon]) is a municipality in the western zone of the Community of Madrid in Spain.

The town is located 15 km west of Madrid's city center, in the western zone of the metro area.

Because of its proximity to the Universidad Europea de Madrid, it has become a university town, with well-developed residential area and amenities for students.

The population reappears in the mid-fifteenth century already with the name of Odón: a handwritten document dated in 1459 attests to a purchase-sale of land and is preserved in the Town Hall.

Already in the early eighteenth century the name of Villaviciosa appeared on official documents, and even alternate the two names, as we can see in a decree of Felipe V that designates the area as "Real Bosque": "He venido en declarar que el nuevo Bosque de la villa de Odón o Villaviciosa, que es propio del Ynfante don Felipe, mi hijo, y sus límites, con sus aumentos o extensiones que en adelante tuviere, son y han de ser Bosque Real, con todos sus privilegios y libertades".
