Henning Schwarz (24 October 1928 – 13 April 1993) was a German politician of the Christian Democratic Union (CDU).
Since 1969, he served in various cabinet positions in the Schleswig-Holstein state government under Minister-Presidents Helmut Lemke, Gerhard Stoltenberg and Uwe Barschel, most of the time as Minister of Justice.
After the 1987 Schleswig-Holstein state election, the CDU lost their absolute majority and the Barschel affair became public.
He himself did not run in that election; CDU candidate for Ministers-President (Spitzenkandidat) instead was his Minister of Justice Heiko Hoffmann.
Schwarz holds the distinction of being the longest-serving interim Minister-President of a German state, serving for the entire 11th legislative term, lasting about eight months.
