Stanislaw Kociolek (3 May 1933, Warsaw – 1 October 2015), often referred to as the "butcher of Tri-City", was a Communist official who served as deputy prime minister of Poland for six months in 1970.
After the fall of Communism, he was charged with crimes committed in Gdansk and Gdynia during the Polish 1970 protests.
Kociolek personally approved the Polish United Workers' Party (PZPR) order issued with Zenon Kliszko, for the regular Army to fire at striking workers in Polish shipyards, which resulted in hundreds of people being killed indiscriminately.
