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 federal constitution; Vienna is a statutory city and as such is a single administrative district in its entirety.

The seats of Bezirksvorsteher (political district head) and Bezirksvertretung (district assembly) are located in the respective districts, with the exception of the 14th district, whose political representatives reside in the 13th district (to which much of the 14th had belonged until 1938). The Magistratisches Bezirksamt (district office of the city administration, not headed by the political district head) in four locations combines services for two districts:

• for the 1st and 8th district in the 1st,
• for the 4th and 5th district in the 5th,
• for the 6th and 7th district in the 7th,
• for the 13th and 14th district in the 13th.

Hence Vienna has 19 district offices.

Since 2002, in Austria, instead of the police the mayors are responsible for objects found in public places. In Vienna, the mayor has ordered the district offices to perform the functions police stations have performed concerning found objects until then. Since 2005, by federal law the districts in all of Austria are responsible for issuing passports and registering residents, tasks until then covered in Vienna by the Federal Police. The mayor of Vienna again has ordered the district offices of the Magistrat to perform these functions.

Optimizing overhead costs has gone farther with the Federal Police in Vienna. The 23 District Police Commands in 2002 have been reduced to 14 City Police Commands. Reducing the number of small districts by mergers, as happened in Berlin after the 1990 reunification of Germany, has not even been discussed in Vienna, since the district assemblies function as breeding factories for the political parties' representatives.
