Alexander Dreyschock (October 15, 1818 - April 1, 1869) was a Czech pianist.

Born at Zak in Bohemia, his musical talents were first displayed publicly at the age of eight. At fifteen he travelled to Prague to study piano and composition with Václav Tomášek. By the age of twenty, Dreyshock undertook his first professional tour in December 1838, performing in various northern and central towns in Germany.

He took things further in 1840, touring Russia (1840-42); Paris (spring 1843); London, Holland, Austria and Hungary (1846); and Denmark and Sweden in 1849. Elsewhere he caused a sensation with prodigious execution of thirds, sixths, and octaves, plus a few other little tricks. When he made his Paris debut in 1843 he included a piece for the left hand alone.

In 1862 Anton Rubinstein invited him to become a staff member at the newly-founded Conservatoire of Music in St Petersburg. He was appointed Professor of Piano, Court Pianist to the Tsar and also Director of the Imperial School of Music for the Operatic Stage. He maintained this double post for six years, but his health suffered from the climate. He moved to Italy in 1868, but it was too late and he died in Venice on 1 April 1869 at the age of fifty-one. At the wish of his family he was buried in Prague.
