Leopold "Poldek" Socha (August 28, 1909 – May 12, 1946) was a Polish sewage inspector in the city of Lwów (now Lviv, Ukraine).
During the Holocaust Socha used his knowledge of the city's sewage system to shelter a group of Jews from Nazi Germans and their supporters of different nationalities.
In 1978 he was recognized by the State of Israel as Righteous Among the Nations.
