Nikolai Vasilievich Artsybushev (Russian: Николай Васильевич Арцыбушев; 7 March [O.S. 23 February] 1858 – 15 April 1937) was a Russian jurist, music publisher and promoter, and minor composer. His name is sometimes seen as Artsibushev, Artsybuchev, Artzibushev, Artzybushev, Artchibousheff, Arcybusev, etc.
Artsybushev was born at Tsarskoye Selo in 1858. His legal studies were at the Imperial School of Jurisprudence in Saint Petersburg, after which he practised in St Petersburg as an attorney. He also dabbled in music composition, and Nikolai Rimsky-Korsakov gave him private lessons in music theory after Mily Balakirev said his works showed some promise. He also became acquainted with the music publisher Mitrofan Belyayev and participated in his regular weekly gatherings called "Fridays" (Vendredis). To mark these occasions, a group of 10 composers including Artsybushev collaborated on a 16-part suite for string quartet, called Les Vendredis. His contribution was a Serenade in A major. He also collaborated with others on Variations on a Russian Theme, in versions for both string quartet and orchestra.
