A Federal Minister for Special Affairs (Bundesminister für besondere Aufgaben) is a federal minister without portfolio of Germany.
Currently, the title is commonly given to the head of the Chancellery to provide him with a vote in cabinet meetings. Historically, appointees have been important political aides or politicians waiting for a portfolio or representatives of certain parties, groups or regions. For instance, several East German politicians were appointed after German reunification in 1990.
