Nikolay Alexandrovich Sokolov (Russian: Никола́й Алекса́ндрович Соколо́в; 26 March [O.S. 14 March] 1859 – 27 March 1922) was a Russian composer of classical music and a member of the circle that grew around the publisher Mitrofan Belyayev.

Sokolov was born in Saint Petersburg in 1859. A student of Nikolai Rimsky-Korsakov, he taught Alexander Tcherepnin, Dmitri Shostakovich and Yuri Shaporin^[1] at the Saint Petersburg Conservatory.

He was the posthumous dedicatee of Shostakovich's Theme and Variations in B-flat major for orchestra, Op. 3.^[2][3]

Sokolov's recorded works include his contributions to several collaborative projects of the "Belyayev circle", including the set of character pieces for string quartet known as Les Vendredis as well as a set of variations for piano and orchestra on a Russian theme.

Other works include a Quintet, Op. 3, also arranged for string orchestra as a serenade; final chorus from Aleksey Konstantinovich Tolstoy's Don Juan, Op. 5; choruses for women's voices, Op. 12 (published 1892); piano variations, Op. 25; Variations on a popular Russian theme for string quartet (published 1899). There are also three string quartets, in F major, A major and D minor, and a string trio in D minor, his Op. 45 (published in 1916). All of these were published by Belyayev's firm.

It is possible that, when Sergei Diaghilev was looking for a composer for The Firebird, Sokolov was considered before Igor Stravinsky was settled on.^[4][5]

He died in Petrograd in 1922, aged 63.
