Gregory Anatolyevich Smirnov (Russian: Григорий Анатольевич Смирнов; 16 March 1949) is a Russian-born choral director, composer, and music instructor based in the San Francisco Bay Area.

[4] In 1991, the San Luis Obispo Vocal Arts Ensemble planned a trip to perform in Russia, and group members Rich and Mary Ferguson were invited to stay with Gregory and his wife Ludmilla in Pskov.

[5] As a faithful Orthodox Christian, he was grateful for the opportunity to perform sacred Russian music that was previously repressed in the Soviet Union.

Gregory has uncovered and performed a number of rare choral works that were hidden from authorities during Soviet times, including ones by Tchaikovsky, Rachmaninoff, and Gretchaninov.

[5][9] In 1993, he conducted a Tchaikovsky rendition of the Cherubic Hymn with the San Luis Obispo Vocal Arts Ensemble that he had discovered on hand-written sheets in a private Russian library.
