Major Theodor Nordmann (18 December 1918 in Dorsten – 19 January 1945 near Insterburg) was a World War II Luftwaffe Stuka ace.

Nordmann joined the Luftwaffe in 1937, and served as a reconnaissance pilot until March 1940, when he transferred to 1./StG 186, flying the Junkers Ju 87 'Stuka'.

StG 1 took part in the invasion of Russia in June 1941 and in September 1941, after 200 operations and 20 tanks destroyed, he was awarded the Knight's Cross.

During the fighting over Orel in the summer of 1942, Nordmann, as Staffelkapitän (squadron leader) of 8./StG 1, made his 600th operational mission, the first Stuka pilot to achieve this total.

He claimed some 80 Soviet tanks destroyed and 43,000 gross register tons (GRT) of merchant shipping sunk.
