Stefan Bembiński (nom de guerre Harnaś - a traditional title for the leader of a Podhallian or Carpathian bandit band)) (born 24 July 1917 in Łagowiec Opatowski; died 1 January 1998) was a Polish veteran of World War II, member of the Home Army, and a Polish senator.
He was captured and imprisoned as a prisoner of war, but he managed to escape and returned to Kobylnik where he resumed work at the school.
Soon he became active in underground anti-Nazi resistance in the Radom Home Army (AK) where he was the commander of a station in Błotnica.
He was the second in command of the section for diversion and sabotage of the Radom Inspectorate and the head of the 72nd Infantry Regiment of the AK.
After the events of the "Polish October" in 1956 he organized in Radom the Society of Fighters for Freedom and Democracy, of which he became the president.
