Hieronymus Weickmann (Russian: Иероним Андреевич Вейкман; 26 February 1825 in Nuremberg – 26 April 1895 in Nuremberg) was an Imperial Russian viola player, composer and music educator of German descent.
Weickmann worked in Saint Petersburg, Russia from 1853 to 1891. He played in the Mariinsky Theatre Orchestra from 1855 to 1890. Along with Leopold Auer, Johann Wilhelm Zacharias Pickel and Karl Davydov, and later Aleksandr Verzhbilovich, he was a member of the quartet of the Russian Musical Society in Saint Petersburg from 1859–1889. He often appeared as viola soloist performing, in particular, the solo part in Hector Berlioz' Harold en Italie conducted by the composer during his tour of Russia in 1867–1868.
Weickmann taught viola at the Saint Petersburg Conservatory from 1863, and was appointed the first Professor of Viola in 1870. Among his students was Vasily Bessel, later a well-known music publisher.
