Jan Hřímalý (Russian: Иван Войцехович Гржимали, also Ivan Voitsekhovich Grzhimali; 13 April 1844 – 24 January [O.S. 11 January] 1915) was an influential Czech violinist and teacher, who was associated with the Moscow Conservatory for 46 years 1869–1915. He was acquainted with Pyotr Ilyich Tchaikovsky, who held him in high regard. He co-premiered Tchaikovsky's String Quartets Nos. 2 (1874) and 3 (1876). In March 1882, he appeared in the first performance (private) of Tchaikovsky's Piano Trio in A minor and may have also appeared in the public premiere in October, although this is not certain.
