Variations and Fugue on an Original Theme, op. 35, "Eroica Variations"

The Variations and Fugue for Piano in E♭ major, Op. 35 are a set of fifteen variations (plus three "bonus" variations) for solo piano composed by Ludwig van Beethoven in 1802. They are commonly referred to as the Eroica Variations because a different set of variations on the opening bass line section were used as the finale of his Symphony No. 3 Eroica composed the following year.
