Vienna (), also known as Electoral District 9 (), is one of the nine multi-member state electoral districts of the National Council, the lower house of the Austrian Parliament, the national legislature of Austria. The electoral district was created as Electoral Union I () in 1923 when electoral regulations were amended to add electoral unions to the existing electoral districts. It was renamed Vienna in 1971 following the re-organisation of electoral districts across Austria. It is conterminous with the city-state of Vienna. The electoral district currently elects 33 of the 183 members of the National Council using the open party-list proportional representation electoral system. At the 2019 legislative election the constituency had 1,149,664 registered electors.

History Electoral Union I was one four electoral unions () established by the "Electoral Regulations for the National Council" () passed by the National Council in 1923 and was conterminous with the city of Vienna. It was divided into seven lower tier electoral districts - Vienna Inner East, Vienna Inner West, Vienna North East, Vienna North West, Vienna South East, Vienna South West and Vienna West - which together had 45 seats. In 1934 the rump National Council (), controlled by the fascist Christian Social Party as the Social Democratic Workers' Party had been banned, imposed the May constitution () which replaced the democratic First Austrian Republic with the corporate authoritarian Federal State of Austria.

The fascists were defeated by the Allies in 1945 and democracy restored. The electoral system which existed prior to 1934, including the electoral districts, were largely restored by the constitutional law of October 1945. The seven lower tier electoral districts in Electoral Union I together had 46 seats. Electoral regulations require the allocation of seats amongst the electoral districts to be recalculated following each national census and in October 1952 the number of seats allocated to Electoral Union I was reduced to 40 based on the population as at the 1951 national census. Liesing, which had been incorporated into the city of Vienna as its 23rd district in 1954, was added to Vienna South West/Electoral Union I in December 1958. The number of seats allocated to Electoral Union I was reduced to 38 in May 1962 based on the population as at the 1961 national census.

The "National Council Election Regulations 1971" () passed by the National Council in November 1970 replaced the lower tier electoral districts with nine state electoral districts () conterminous with the nine states of Austria. Two upper tier electoral unions were created and Vienna was grouped together with the states of Burgenland and Lower Austria to form Electoral Union I (also known as Electoral Union East). The newly created Vienna electoral district was initially allocated 42 seats in January 1971. The number of seats allocated to Vienna was reduced to 39 in February 1972 based on the population as at the 1971 national census. The number of seats allocated to Vienna was reduced to 35 in February 1982 based on the population as at the 1981 national census. However, in December 1982 the Constitutional Court ruled that this allocation of seats was unlawful and in February 1983 the number of seats allocated to Vienna was increased to 36.

The "National Council Electoral Regulations 1992" () passed by the National Council in 1992 established 43 regional electoral districts (), a new third tier of electoral districts, whilst keeping the state electoral districts. Vienna was divided into seven regional electoral districts - Vienna Inner East, Vienna Inner South, Vienna Inner West, Vienna North, Vienna North West, Vienna South and Vienna South West. Vienna was allocated 34 seats in May 1993. The number of seats allocated to Vienna was reduced to 33 in September 2002 based on the population as at the 2001 national census.

Electoral system 1994 to date Vienna currently elects 33 of the 183 members of the National Council using the open party-list proportional representation electoral system. The allocation of seats is carried out in three stages. In the first stage, seats are allocated to parties (lists) at the regional level using a state-wide Hare quota () (valid votes in the state divided by the number of seats in the state). In the second stage, seats are allocated to parties at the state/provincial level using the state-wide Hare quota (any seats won by the party at the regional stage are subtracted from the party's state seats). In the third and final stage, seats are allocated to parties at the federal/national level using the D'Hondt method (any seats won by the party at the regional and state stages are subtracted from the party's federal seats). Only parties that reach the 4% national threshold, or have won a seat at the regional stage, compete for seats at the state and federal stages.

Electors may cast one preferential vote for individual candidates at the regional, state and federal levels. Split-ticket voting (panachage), or voting for more than one candidate at each level, is not permitted and will result in the ballot paper being invalidated. At the regional level, candidates must receive preferential votes amounting to at least 14% of the valid votes cast for their party to over-ride the order of the party list (10% and 7% respectively for the state and federal levels). Prior to April 2013 electors could not cast preferential votes at the federal level and the thresholds candidates needed to over-ride the party list order were higher at the regional level (half the Hare quota or of the party votes) and state level (Hare quota).

1971 to 1994 Allocation of seats was carried out in two stages. In the first stage, seats were allocated to parties at the state level using the Hare quota. In the second stage, surplus votes and unallocated seats from the first stage were aggregated at the electoral union level and allocated to parties using the D'Hondt method. Only parties that won a seat at the state stage, in any state, competed for seats at the electoral union stage. Electors could cast one preferential vote for individual candidates at the state level but a candidate needed to receive preferential votes amounting to at least the Hare quota to over-ride the party list order. The allocation of seats to candidates at the electoral union level was based solely on party list order i.e. a closed list.

1923 to 1971 Allocation of seats was carried out in two stages. In the first stage, seats were allocated to parties at the district level using the Droop quota (also known as the Hagenbach-Bischoff method). In the second stage, surplus votes and unallocated seats from the first stage were aggregated at the electoral union level and allocated to parties using the D'Hondt method. Only parties that won a seat at the district stage, in any district, competed for seats at the electoral union stage.

Electors could also cast preferential votes for individual candidates either by voting for the list in the order submiited by the party or by ranking the candidates in preferred order. Candidates were then awarded points using the Borda count with the top candidate receiving as many points as there were candidates on the list etc. If a voter choose to rank individual candidates but did not award rankings to some the candidates on the list, these candidates were awarded the remaining points in order of their position on the party list. If a voter had struck out any candidate on the list that candidate did not receive any points. The seats won by the party were allocated to the candidates with the most points on the list.
