Waldemar Koch (25 September 1880 – 15 May 1963) was a German liberal politician and economist.
He was born in Bad Harzburg, Duchy of Brunswick. Koch studied Economics, Philosophy and History at Berlin. He received a doctorate in 1907 for a dissertation titled "Consolidation in the German Electrical Industry" ("Konzentration in der dt. Elektroindustrie").
After World War II he co-founded the Liberal Democratic Party of Germany (LDPD) in the Soviet Occupied Zone (SBZ). In 1945 he was briefly the Chairman of the LDPD, but the Soviets forced him to resign after a few months. He opposed the land reform plans of the Soviet authorities and the Socialist Unity Party (SED). Koch was a member of the LDPD's executive committee until 1948.
In 1949 he went to West Germany (West Berlin) and again worked as an economics professor. From 1948 to 1956 Koch was a member of the liberal FDP (Free Democratic Party).
