The first Müller senate was the state government of Berlin between 2014 and 2016, sworn in on 11 December 2014 after Michael Müller was elected as Governing Mayor by the members of the Abgeordnetenhaus of Berlin.

It was formed after the resignation of Governing Mayor Klaus Wowereit, and was a continuation of the grand coalition of the Social Democratic Party (SPD) and Christian Democratic Union (CDU) formed after the 2011 Berlin state election.

Wowereit announced his resignation in August 2014, citing continued delays in the opening of the Berlin Brandenburg Airport, which he described as his "biggest failure".

Candidates standing for election were Senator for Urban Development Michael Müller, SPD parliamentary leader Raed Saleh, and former state SPD chairman Jan Stöß.

[3] Müller was elected as Governing Mayor by the Abgeordnetenhaus on 11 December, winning 87 votes out of 145 cast.
