Wojciech Kossak (Paris, France, December 31, 1857 – July 29, 1942, Kraków, Poland) was a Polish painter and member of the celebrated Kossak family of painters and writers. He was the son of painter Juliusz Kossak, the twin brother of freedom fighter Tadeusz Kossak, and the father of painter Jerzy Kossak.
Wojciech Kossak's historical painting was very different in style and subject matter from that of his predecessor Jan Matejko's. Kossak belonged to a new generation of Polish battle-scene artists influenced by the work of his father Juliusz. However, similar to Matejko, he is known for depicting the history of Polish armed struggle and notable Polish battles of Central and Eastern Europe against the foreign oppressors. Among his most famous paintings is The Racławice Panorama.
