Carl Friedrich Freiherr von Langen (25 July 1887 – 2 August 1934) was a German landowner, cavalry officer, and equestrian who was a gold medalist at the 1928 Summer Olympics.

Langen was born in Klein Belitz in the Grand Duchy of Mecklenburg-Schwerin, the son of an aristocratic estate owner and horse breeder.

[2] In the autumn of 1930, Langen became a member of the Sturmabteilung (SA), the paramilitary organization of the Nazi Party, attaining the rank of SA-Sturmbannführer.

He died in Potsdam as a result of internal injuries sustained in a fall on 15 July 1934, during a competition at the Döberitz military training area.

In 1941, the Nazi government under Reich Propaganda Minister Joseph Goebbels, produced a film based on Langen's life with the title Riding for Germany, which contained nationalist and antisemitic content.
