Ludwig Steeg (22 December 1894 – 6 September 1945) was a German Nazi politician who was the Oberbürgermeister (Lord Mayor) and Stadtpräsident (City President) of Berlin during the Third Reich.

He joined the Nazi Party in 1933 (membership number 1,485,884) and thus gained rapid promotion as the majority of Berlin's civil servants who were loyal to the Social Democrats were removed from office.

The real power in Berlin under the Nazis was, however, the Party Gauleiter (Regional Leader), Joseph Goebbels, and in July 1940 he persuaded Adolf Hitler to dismiss Lippert, who he believed had become a rival to his authority.

At the time of the first severe raid on 23–24 August 1943, Goebbels blamed Steeg for the poor performance of municipal authorities and threatened to dismiss him if matters failed to improve.

By December 1943, Hitler wanted to settle the question of a permanent political leadership for Berlin and asked Goebbels to take on the job of Stadtpräsident while Steeg would be relegated to the more ceremonial post of Oberbürgermeister.
