Rainer Michael Müller (born 9 December 1964) is a German politician of theSocial Democratic Party (SPD) who served asGoverning Mayor of Berlin from 2014 to 2021. He served as a member of the GermanBundestag from2021 to2025, representing theBerlin-Charlottenburg-Wilmersdorf district.
He was alsoPresident of the Bundesrat from November 2017 until October 2018, which made him deputy to thePresident of Germany.[1]
Müller was elected to theBerlin House of Representatives in 1996 and has been a member ever since. On 16 June 2001, he took over leadership of theSPD Group in theHouse of Representatives from Klaus Wowereit who had been elected Governing Mayor of Berlin. After the resignation of Peter Strieder in April 2004, Müller ran for the Berlin SPD State Party Leadership and won, remaining the Leader of Berlin SPD until he lost his re-election bid against Jan Stöß in June 2012.[2]
Following the2011 state elections in Berlin, Müller was senator for urban development and the environment from 1 December 2011 to 11 December 2014. One of his most extensive projects, which planned to build business space and apartments on the grounds of the formerTempelhof Airport, was rejected in 2014 by a clear majority of Berlin citizens in a referendum.[3]

In December 2014, Müller took over in midterm from the incumbentKlaus Wowereit, Berlin's longest-serving mayor since reunification in 1990,[4] who presided over the city's emergence as a popular tourist destination and center for high-tech start-ups but stepped down after his popularity suffered from the debacle around theBerlin Brandenburg Airport.[5]
Müller had previously made a surprise entry into the race to succeed Wowereit and defeated two candidates initially seen as the most likely successors.[4] Shortly before the election, Müller ran for the Leadership of the Social Democratic Party in Berlin a second time, and won. In the2016 Berlin Election, he led the party to victory, albeit not without some losses. After the election, Müller ended the grand coalition with theChristian Democratic Union and formed a new government with theGreen Party and the left-wingDie Linke.
As one of the state's representatives at theBundesrat, Müller served on the Committee on Foreign Affairs, the Committee on European Affairs and the Committee on Cultural Affairs from 2014.
Müller was an SPD delegate to theFederal Convention for the purpose of electing thePresident of Germany in 2004, 2009 and 2012. In the negotiations to form acoalition government under the leadership ofChancellorAngela Merkel following the2017 federal elections, he was part of the working group on urban development, led byBernd Althusmann,Kurt Gribl andNatascha Kohnen.
In August 2020, Müller announced his intention to leave state politics and instead run as a candidate in the2021 national elections.[6] In the negotiations to form a so-calledtraffic light coalition of the SPD, theGreen Party and theFree Democrats (FDP) on the national level following the elections, he was part of his party's delegation in the working group on innovation and research, co-chaired byThomas Losse-Müller,Katharina Fegebank andLydia Hüskens.[7]
In parliament, Müller served on the Committee on Foreign Affairs (2021–2025)[8] and its Subcommittee on Foreign Cultural and Educational Policy (2022–2025).[citation needed] He also chaired a study commission set up to investigate the entire period of German involvement in Afghanistan from 2001 to 2021 and to draw lessons for foreign and security policy in future.[9]
In addition to his committee assignments, Müller chaired the German-Japanese Parliamentary Friendship Group.[citation needed]
