Alexander Johann Heinrich Friedrich Möller (26 April 1903 – 2 October 1985)[1] was a German politician of the Social Democratic Party (SPD).

After the war, he served in the Landtag of Baden-Württemberg from 1946 to 5 October 1961, when he was elected to the Bundestag.

From 1969 to 1971, Möller served as Federal Minister of Finance in the Cabinet of Willy Brandt.

Besides being active in the SPD, Möller was director general of and Chief Executive Officer of the Karlsruher Lebensversicherung AG.

Hence, his nickname was Genosse Generaldirektor (roughly: Comrade director general), which he also used as a title of his memoirs (1978).
