Aleksander L'vovich Gurilyov (3 September [O.S. 22 August] 1803 – 11 September [O.S. 30 August] 1858) was a notable Russian composer, pianist, violinist, and music teacher. Born in Semyonovskoye, Serpukhov Oblast, Russia, into a family of serf musicians under Count V.G. Orlov, Gurilyov received his initial musical education from his father, Lev Gurilyov, who was a kapellmeister. He further honed his skills under the tutelage of the renowned pianist John Field and composer Iosif I. Genishta.

After being emancipated from serfdom in 1831, Gurilyov moved to Moscow, where he became a prominent figure in the musical and literary circles. He composed over 200 works, including more than 60 songs characterized by romantic and sentimental themes. His compositions, such as "The Bell is Ringing Monotonously," "And Boring and Sad," and "Parting," were widely appreciated and published by notable publishers like Bernard.

Gurilyov's music often featured dance rhythms like the mazurka, polka, and waltz, and he was known for his lyrical romances and piano compositions. Despite his success, Gurilyov lived in poverty, working as a private music teacher and editor. His later years were marred by paralysis and mental illness, leading to his death in Moscow in 1858. His friendship with composer Alexander Egorovich Varlamov provided some solace during his challenging life. Gurilyov's legacy includes a rich collection of romances, folk song arrangements, and piano pieces that continue to be celebrated in Russian music history.
