Václav Boštík (1913, Horní Újezd – 2005, Prague) was a Czech painter, graphic artist, typographer, restorer, art theoretician and poet.
Between 1933 and 1937 he studied at the University of Architecture and Structural Engineering at the Czech Technical University and the Faculty of Science at Charles University. He started at the Academy of Fine Arts in Prague in 1937.
Early in his artistic career, he foregoes traditional realism painting, and during the 1950s achieved his unique style, characterised by abstract minimalistic expression with a strong philosophical and theological starting point. Boštík explored simple geometric shapes in which he portrayed the play of light in a given colour combination. During the latter half of the 1950s, Boštík and the artist Jiří John created a memorial to victims of the Holocaust in Prague's Pinkas Synagogue. Starting with the 1960s, Boštik created works depicting space, or cosmogenic processes, in which the canvas was perceived as a scientific experiment. He also made a couple of stage curtains and designs for stained glass windows.
He was a member of the Umělecká beseda group, active from 1942 until 1972 (and later revived after 1989). In 1960 he became one of the founding members of the UB 12 Group with Václav Bartovský. The group significantly influenced the development of Czech art during the 1960s (other: Adriena Šimotová, Stanislav Kolíbal, Vladimír and Věra Janoušeks and Jiří John). Boštík was a member of the Art Union New group from 1988 until 1990.
