Zdzisław Marchwicki (18 October 1927 – 26 April 1977), known as The Zagłębie Vampire (Polish: Wampir z Zagłębia), was an alleged Polish serial killer who, together with several accomplices, was convicted of killing 14 women and attacking 7 others around the country from 1964 to 1970. For this, Marchwicki was executed in 1977, but since then his guilt has been questioned.
