Spain uses the designation "autonomous" for two types of its administrative subdivisions:

Autonomy is asymmetrical in Spain. Both the autonomous communities and the autonomous cities (collectively known as "the Autonomies") constitute the first order (highest) level of territorial organization of Spain.
