The districts of Vienna (German: Wiener Gemeindebezirke) are the 23 named city sections of Vienna, Austria, which are numbered for easy reference. They were created from 1850 onwards, when the city area was enlarged by the inclusion of surrounding communities. Although they fill a similar role, Vienna's municipal districts are not administrative districts (Bezirke) as defined by the constitution; Vienna is a statutory city and as such is a single administrative district in its entirety.
