Friedrich Adolf Ferdinand, Freiherr von Flotow (27 April 1812 – 24 January 1883) was a German composer. He is chiefly remembered for his opera Martha, which was popular in the 19th century.

Flotow was born in Teutendorf, in Mecklenburg, into an aristocratic family. He studied at the Conservatoire de Paris and came under the influence of Auber, Rossini, Meyerbeer, Donizetti, Halévy, and later Gounod and Offenbach. These influences are reflected in his operas, where a distinctive French opéra comique flavour exists.
