Bertram Wieczorek (born 16 January 1951) is a German physician and former politician (CDU). He served as parliamentary undersecretary in the East German Ministry for Defence and Arms Procurement between March and October 1990. After navigating the political upheavals of 1990 he served between 1991 and 1994 as parliamentary undersecretary in the German Ministry for the Environment, Nature Conservation, Building and Nuclear Safety. His subsequent career in charge of the Berlin Water Company between 1994 and 1999 was not without controversy.
