Jadwiga Apostoł-Staniszewska (22 December 1913 – 2 February 1990) was a Polish teacher in the interwar period, an underground activist during World War II, and a writer in postwar Poland.

After the Soviet liberation – as the only executive-member of the Tatra Confederation who was still alive – she was persecuted by the Ministry of Public Security and sentenced to five years in prison on trumped-up charges.

[3][4] In May 1941, Apostoł joined the Tatra Confederation (KT), a resistance group formed in Nowy Targ by Augustyn Suski and Tadeusz Popek to oppose the Nazi Goralenvolk action aimed at the germanization of the Polish highlanders.

She became the KT executive secretary in charge of organizational and administrative duties, writing announcements for clandestine newsletters and typing all the group's printed material.

She moved between Skomielna, Jordanów, and Bogdanówka near Myślenice, where she was finally turned in by an informant and arrested along with her co-conspirator Tadeusz Popek on 22 August 1942.

On January 18, 1945, she was part of the forced evacuation of the camp, the Death March, from Auschwitz to Wodzisław Śląski, from which she was transported to Ravensbrück, along with the rest of the female prisoners and taken to its Malchow sub-camp.
