Jerzy Kukuczka (March 24, 1948 – October 24, 1989) was a Polish alpine and high-altitude climber.
On September 18, 1987, he became the second man, after Reinhold Messner, to climb all fourteen eight-thousanders in the world. He is the first man who made the first winter ascents of three eight-thousanders: Dhaulagiri with Andrzej Czok in 1985, Kangchenjunga with Krzysztof Wielicki in 1986 and Annapurna I with Artur Hajzer in 1987. Only Simone Moro did better than him, after climbing the fourth over-8000 peak in winter in 2016. Along with Tadeusz Piotrowski, Kukuczka established a new route on K2 (the so-called “Polish Line”), which no one has ever repeated.
