Stefan Czarniecki of the Łodzia coat of arms (1599 – 16 February 1665) was a Polish–Lithuanian Commonwealth general and nobleman. In his career he rose from a petty nobleman to a magnate holding one of the highest offices in the Commonwealth, something that was unprecedented in the Commonwealth history. On 22 July 1664 he received the office of the voivode of Kiev and on 2 January 1665, a few weeks before his death, he was given the office of Field Hetman (one of top military commanders) of the Crown of the Polish Kingdom. He is remembered as an accomplished military commander, and regarded as a Polish national hero. His status in Polish history is acknowledged by a mention of his name in the Polish national anthem.
