Tikhon Nikolayevich Khrennikov (Russian: Тихон Николаевич Хренников; 10 June [O.S. 28 May] 1913 – 14 August 2007) was a Russian and Soviet composer, pianist, and General Secretary of the Union of Soviet Composers (1948–1991), who was also known for his political activities. He wrote three symphonies, four piano concertos, two violin concertos, two cello concertos, operas, operettas, ballets, chamber music, incidental music and film music.

During the 1930s, Khrennikov was already being hailed as a leading Soviet composer. In 1948, Andrei Zhdanov, the leader of the anti-formalism campaign, nominated Khrennikov as Secretary of the Union of Soviet Composers. He held this influential post until the collapse of the Soviet Union in 1991.
