Stefania "Stefa" Wilczyńska (26 May 1886 – 6 August 1942) was a Polish educator who was murdered in the Holocaust.

[3] During World War I, Korczak was called up for military service and Wilczyńska had to manage the orphanage by herself.

In August 1942, as part of the Kinderaktion, residents of Jewish orphanages were deported to the gas chambers at Treblinka.

Korczak, Wilczyńska and the staff of the orphanage were given the option of avoiding the deportation, but chose to remain with the orphans.

[1][2] A plaque dedicated to the memory of Wilczyńska has been placed at the original site of the orphanage.
