Ivan the Terrible, Op. 116, is the score composed by Sergei Prokofiev for Sergei Eisenstein's film Ivan the Terrible (1942–45) and its sequel (1946), the first two parts of an incomplete trilogy. The project was Prokofiev's second collaboration with Eisenstein, the first being the popular Aleksandr Nevskiy (1938). In 1973 the composer Mikhail Chulaki and choreographer Yuri Grigorovich drew on Prokofiev's film scores to create the ballet Ivan the Terrible, which was given its premiere in 1975.
