Alexander Nevsky is the score composed by Sergei Prokofiev for Sergei Eisenstein's 1938 film Alexander Nevsky. The subject of the film is the 13th century incursion of the knights of the Livonian Order into the territory of the Novgorod Republic, their capture of the city of Pskov, the summoning of Prince Alexander Nevsky to the defense of Rus', and his subsequent victory over the crusaders in 1242. The majority of the score's song texts were written by the poet Vladimir Lugovskoy.

Sergei Sergeyevich Prokofiev was a Russian composer, pianist, and conductor who later worked in the Soviet Union. As the creator of acknowledged masterpieces across numerous music genres, he is regarded as one of the major composers of the 20th century. His works include such widely heard pieces as the March from The Love for Three Oranges, the suite Lieutenant Kijé, the ballet Romeo and Juliet—from which "Dance of the Knights" is taken—and Peter and the Wolf. Of the established forms and genres in which he worked, he created—excluding juvenilia—seven completed operas, seven symphonies, eight ballets, five piano concertos, two violin concertos, a cello concerto, a symphony-concerto for cello and orchestra, and nine completed piano sonatas.
