Mezhdunarodnaya Kniga (MK) (meaning International Books) is a Russian company responsible for the export of Russian (formerly Soviet) books, periodicals, stamps and music to other countries of the world.

During the Soviet era, MK had a monopoly over the export of music records.

Vladimir Lenin signed a decree on 14 June 1921 titled "Law on Acquiring and Distributing Foreign Literature", that established a Russian – German joint stock company called "Kniga" in Berlin.

In 1922 its Moscow branch office was established under the name "Mezhdunarodnaya Kniga" MK.

This new entity describes itself as “Daughter Company” of Mezhdunarodnaya Kniga, and works as a distributor of Russian books in foreign countries.
