Carl Ferdinand Langhans (14 January 1782 - 22 November 1869) was a Prussian architect whose specialty was designing theaters.
Born in Breslau, Silesia, Langhans was the son of the architect Carl Gotthard Langhans.
Langhans' designs included the reconstruction of the Berlin State Opera after a fire and the New Theatre in Leipzig (destroyed by Allied bombing in World War II). Other projects included theaters in Breslau and Liegnitz, and the Berlin residence (the Old Palace) of William I, German Emperor. He is also remembered for his innovative pleorama entertainment.
Langhans died in Berlin. His grave is preserved in the Protestant Friedhof III der Jerusalems- und Neuen Kirchengemeinde (Cemetery No. III of the congregations of Jerusalem's Church and New Church) in Berlin-Kreuzberg, south of Hallesches Tor.
