Krzysztof Kamil Baczyński, (code-name Jan Bugaj, 1921-1944) - Polish poet and Home Army soldier.

Baczyński was born in Warsaw in the family of renowned literary critic Stanisław Baczyński . During the German occupation of Poland he started cooperation with left-wing underground press, most notably with the "Płomienie" (Flames) and "Droga" (Way) magazines. At the same time he was a student of Polish language faculty at the secret underground Warsaw University and the "Agricola " Home Army NCOs School.

On July 6, 1942 he married Barbara Drapczyńska, his university colleague. The effect of this marriage was a set of erotics written by Baczyński, reputedly one of the most notable in Polish language. Shortly before the Warsaw Uprising Baczyński gave a copy of all his poems to one of his friends to hide it in Żoliborz area. Because of that they survived the war.

As a member of Boy Scouts Storming Groups (Harcerskie Grupy Szturmowe) Baczyński took part in many sabotage actions throughout the occupation. After the Warsaw Uprising broke out he joined the "Parasol" battalion. He was killed in action by a German sniper on August 4, 1944 in Blank Palace (Pałac Blanka) in Warsaw Old Town area. He is buried on Powązki Cemetery together with his wife who was killed on September 1, 1944.

In his poems and short novels Baczyński showed both romantic traditions and catastrophism. His poems depict the brutality of war and love as the only force to effectively defend a human being against it.
