Ludwig Stiegler (born 9 April 1944 in Parsberg) is a German politician.

Afterwards he studied law, sociology and political science in Bonn and Munich.

In 2003 he was elected chairman of the SPD in the state of Bavaria and held this office until 2009.

In July 2002 he said that the CDU and FDP didn't have the right to criticize then Federal Minister of the Interior and former RAF-lawyer Otto Schily in relation to the attempt to ban the far-right NPD, because "the forerunners of CDU and FDP helped bring Adolf Hitler to power."

In July 2005 he said that the only thing that came to his mind in relation to the CDU/CSU's slogan during the election campaign Sozial ist, was Arbeit schafft!
