Václav Jan Křtitel Tomášek (17 April 1774, Skuteč, Bohemia - 3 April 1850, Prague) was a Czech composer and music teacher.
As a pianist, he was an autodidact, becoming one of the most important piano teachers of Prague for a century. Until 1824 he worked as a piano teacher in aristocratic families. Afterwards he created a considerable school of music; among its most well-known pupils were Jan Voříšek, Alexander Dreyschock and Eduard Hanslick. Tomášek made the acquaintance of Beethoven, and also of Goethe, whose poems he set. He maintained correspondence with the Polish pianist and composer Maria Agata Szymanowska. His autobiography was published in German, as well as in a Czech translation. He lived at number 15 Tomášská Street in Prague - the building bears a memorial plaque to him in Czech and German.
Tomášek wrote a good deal for the piano and became a forerunner of the lyric piano piece which later reached its apogee in the works of Schubert and Chopin. At first he remained loyal to the Classical style, but later was influenced by the newly born Romanticism. An important part of his oeuvre are his songs. Besides songs to Goethe's German poems he composed also songs to the patriotic lyrics of Czech authors. He composed short pieces for glass harp and organ, and works for choir.
In 1823-1824, he was one of the 50 composers who composed a variation on a waltz by Anton Diabelli for Vaterländischer Künstlerverein.
