The Greens – The Green Alternative (German: Die Grünen – Die Grüne Alternative, pronounced [diː ˈɡʁyːnən diː ˈɡʁyːnə ˌaltɛʁnaˈtiːvə]) is a green political party in Austria. The Greens currently sit in opposition. Formerly, they were part of the Schallenberg government, the Second Kurz government, and the Nehammer government. It won 8.2% of votes cast in the 2024 Austrian legislative election. The current President of Austria, Alexander Van der Bellen, is from the Green Party.

The party was founded in 1986 under the name "Green Alternative" (Grüne Alternative), following the merger of the more conservative Green party Vereinte Grüne Österreichs (United Greens of Austria VGÖ, founded 1982) and the more progressive party Alternative Liste Österreichs (Alternative List Austria, ALÖ, founded 1982). Since 1993, the party has carried the official name Die Grünen – Die Grüne Alternative (Grüne), but refers to itself in English as "Austrian Greens". There are still differences between the former members of the old Alternative and VGÖ factions within the party, reflected in the differing approaches of the national and state parties.

Apart from ecological issues such as environmental protection, the Greens are Pro-European and campaign for the rights of minorities and advocate a socio-ecological (ökosozial) tax reform. Their basic values according to their charter in 2001 are: "direct democracy, nonviolence, ecology, solidarity, feminism and self-determination". The party is a member of the European Green Party and Global Greens.

In 1978 the Austrian Green movement began with the successful campaign to prevent the opening of the nuclear power plant in Zwentendorf (which had been favoured by Bruno Kreisky's government), the Green Party was born in 1984 during the sit-in protests which prevented the Danube power plant at Hainburg from being built.

In the 1986 parliamentary elections the Green Party started off with 4.82% of all votes cast and entered parliament with eight National Council mandates. In the early elections to National Council in 2002, the Green Party nationwide received 9.47% of votes, and won 17 mandates to the National Council. At that time, it was the highest number of votes garnered by any European Green party.

When the Greens took their seats in parliament for the first time, they chose to appear somewhat unconventional. They initially refused to adapt their behaviour to that of the other parties; an example of this is their refusal to elect a chairperson (Klubobmann/Klubobfrau) and designated a puppet made out of straw instead. Delegates would appear in parliament dressed in casual wear such as jeans and trainers. Worldwide attention was drawn when the Green delegate Andreas Wabl hoisted a swastika flag on the speakers podium in the Austrian parliament, protesting against then Federal President Kurt Waldheim.

After the national election in 2002, the Greens entered into preliminary negotiations about a possible coalition government with the conservative ÖVP. During negotiations, party leadership was accused of internally black-mailing skeptical members. Negotiations between the two parties were subsequently called off, after the results with the ÖVP were not sufficient. The Green youth organisation Grünalternative Jugend (Green Alternative Youth or GAJ) briefly occupied the rooms of the Green parliamentary club in the Austrian parliament building in protest.

In 2003 three Green federal counsellors formed their own club in the Upper House Federal Council (Bundesrat) of Parliament.
