Jakub Obrovský (December 24, 1882 – March 31, 1949) was a Czechoslovak artist, sculptor and writer.

He studied at the School of Applied Arts in Prague with Celda Klouček, EK Liška and Stanislav Sucharda (1897-1901) and continued his studies at the Academy of Fine Arts with Max Pirner (1901-1905).

In 1919 he became a professor at the Academy of Fine Arts, and later served as the rector.

He designed early stamps of the new Republic of Czechoslovakia: the lion escaping from its chains (28 October 1919) and the allegory of economy (1920).

His daughter Jana Obrovská (1930 – 1987) became a noted Czech composer.
