The Third Merkel cabinet was the 23rd Government of the Federal Republic of Germany during the 18th legislative session of the Bundestag. Installed after the 2013 federal election, it left office on 14 March 2018. It was preceded by the second Merkel cabinet and succeeded by the fourth Merkel cabinet. Led by Chancellor Angela Merkel. The government was supported by a coalition of the Christian Democratic Union (CDU), the Christian Social Union of Bavaria (CSU) and the Social Democrats (SPD). Sigmar Gabriel (SPD) replaced Philipp Rösler (FDP) as Vice Chancellor of Germany and became Federal Minister for Economics and Energy.

Federal elections were held on 22 September to elect the members of the 18th Bundestag of Germany. At stake were all 598 seats to the Bundestag, plus 33 overhang seats determined thereafter. The Christian Democratic Union of Germany/Christian Social Union of Bavaria (CDU/CSU) of incumbent chancellor Angela Merkel won their best result since 1990 with nearly 42% of the vote and nearly 50% of the seats, just five short for an overall majority. The Free Democratic Party (FDP) failed to meet the 5% vote electoral threshold in what was their worst showing ever in a federal election, denying them seats in the Bundestag for the first time in their history.
