There have been a number of red–green governments in Europe since the 1990s.

• InGermany, a red–green coalition of the Social Democratic Party of Germany (SPD) and Alliance '90/The Greens led by Chancellor Gerhard Schröder formed the federal government from September 1998 to September 2005.
• InFrance, the 'Plural Left' coalition of the Socialist Party (PS), The Greens, French Communist Party and allies governed from 1997 until 2002. The Ayrault government which governed from May 2012 until March 2014 had ministers affiliated with the PS, Radical Party of the Left (PRG) and Europe Ecology – The Greens. The second Valls government (August 2014 to December 2016) and Cazeneuve Government (December 2016 to May 2017) were both formed of ministers from the PS, PRG and Ecologist Party.
• InFinland, Prime Minister Paavo Lipponen's first and second cabinets contained ministers from the Social Democratic Party of Finland (SDP), including Lipponen himself, and the Green League. The Green League participated in government from April 1995 until May 2002. The Rinne Cabinet formed in June 2019 is formed by the SDP as largest party, in coalition with the Green League, agrarian Centre Party, Swedish People's Party and Left Alliance.
• InNorway, the Red-Green Coalition of the Labour Party, Socialist Left Party and Centre Party governed Norway as a majority government from the 2005 general election until 2013. The 'green' element was the Centre Party, an agrarian party with green as its official color.

However, unlike a straightforward red–green alliance, these centre-left cabinets involved a broad range of political parties that were Catholic-inspired Christian left, social-liberal and even communist backgrounds.
• InDenmark, the Thorning-Schmidt government, which governed from October 2011 to February 2014, contained the Social Democrats as the largest party in coalition with the Social Liberals and Socialist People's Party, the latter being a green party and member of the European Green Party and Global Greens.

This coalition was renewed on 21 January 2019 as the Löfven II Cabinet and 9 July 2021 as the Löfven III Cabinet, before being replaced on 30 November 2021 by the Andersson Cabinet, formed by the Social Democrats alone with external support from the Greens, Left Party and agrarian Centre Party.
• InPortugal, the First António Costa Cabinet established on 26 November 2015 was a minority government led by the Socialist Party with external support from the Left Bloc, Portuguese Communist Party and The Greens, which governed until 26 October 2019.

Ared–red–green coalitionorred–green–red coalition is a left-wing alliance of two "red" social democratic, democratic socialist, or socialist parties with one "green" environmentalist party. In France, Jean-Luc Mélenchon's New Ecologic and Social People's Union is an example of a left–green alliance.^[1][2]

Political parties or joint electoral lists have been formed over the years, most often between socialists and left-oriented greens. Example include:

• GreenLeft of the Netherlands: a political party that began in 1989 as a political alliance comprising the Communist Party of the Netherlands, Pacifist Socialist Party and the Christian left parties Evangelical People's Party and Political Party of Radicals. The alliance had been known as Rainbow for the 1989 European elections.
• Unity List – The Red–Greens of Denmark: a political party, originally a political alliance, formed in 1989 by the Left Socialists (VS), Communist Party of Denmark (DKP) and Socialist Workers Party (SAP).
• The Nordic Green Left Alliance was a European political alliance formed by the Left Alliance (Finland), the Left-Green Movement (Iceland), the Left Party (Sweden), the Socialist Left Party (Norway) and the Socialist People's Party (Denmark). The MEPs of the NGLA sat in the European United Left–Nordic Green Left (GUE/NGL) group in the European Parliament, although the MEPs of the Socialist People's Party sat in The Greens–European Free Alliance (G/EFA) group and later joined the European Green Party.
• Left Ecology Freedom (SEL): a former political party in Italy that was initially formed as a political alliance comprising socialists, greens and social democrats. The political alliance was itself a partial successor to the short-lived The Left – The Rainbow electoral alliance which had existed in Italy from December 2007 until May 2008 comprising the Federation of the Greens (FdV), the Communist Refoundation Party, Party of Italian Communists and the Democratic Left (SD). In 2022 a new alliance, Greens and Left Alliance, composed of the successor of SEL and SD Italian Left and the successor of FdV Green Europe, was formed.
• The Coalition of the Radical Left (SYRIZA), a Greek party formed by the merger of a broad set of left-wing and eco-socialist parties, many of which were themselves formerly red–green alliances, such as the Coalition of Left, of Movements and Ecology (Synaspismos), Renewing Communist Ecological Left (AKOA), and Ecosocialists of Greece. The SYRIZA-led cabinet of Alexis Tsipras contains ones junior minister, Giannis Tsironis, from the Ecologist Greens.
