Alexander Ilyinsky (1859 - 1920) was a Russian music teacher and composer, best known for the Lullaby (Berceuse), Op. 13, No. 7, from his orchestral suite "Noure and Anitra", and for the opera The Fountain of Bakhchisaray set to Pushkin's poem of the same name.
His music studies were in Berlin, under Theodor Kullak and Natanael Betcher at the Berlin Conservatory, and under Woldemar Bargiel at the Neue Akademie der Tonkunst.
He returned to Russia in 1885, graduated from the St Petersburg Conservatory and taught at the Moscow Philharmonic Society School of Music and Drama. He resigned in 1899 and started giving private lessons. In 1905 he joined the staff of the Moscow Conservatory. His students included Vasily Kalinnikov, Anatoly Nikolayevich Alexandrov, Nikolai Roslavets, Elena Stanekaite-Laumyanskene, and the Finnish composer Väinö Raitio.
