Announcing her death on Wednesday, Deputy Culture Minister Maciej Wróbel called her "a heroine of many generations" and "an authority who spoke out on important issues, opposed hate speech and ordinary evil."
He said she "wanted a strong and safe Poland for us in Europe."
Traczyk-Stawska died on Tuesday, state news agency PAP reported.
Born on April 7, 1927 in Warsaw, Traczyk-Stawska joined the underground resistance during World War II as a teenager.
In 1942, she became involved with the Grey Ranks, a clandestine Polish scouting organisation, painting resistance symbols on walls and distributing underground leaflets.
Her duties also included delivering death sentences issued by the Polish underground to collaborators and informers, a task that required direct contact with the recipients and carried significant personal risk.
During the Warsaw Uprising, she served as a courier and fighter in a unit protecting military publishing facilities.
She took part in fighting in central Warsaw, including around Marszałkowska, Bracka and Chmielna streets, as well as in the Powiśle district.
She was also involved in heavy fighting around the Holy Cross Church and a police headquarters.
Wounded in mid-September 1944, she continued fighting until the uprising's capitulation. She spent the final months of the war in German captivity.
After the war, she continued her education abroad, studying in Italy and later in Palestine before returning to Poland in 1947.
She went on to study psychology at the University of Warsaw and worked for many years as a teacher in special education schools.
In the decades that followed, Traczyk-Stawska became actively involved in preserving the memory of fallen insurgents.
She helped initiate the establishment of a national day of remembrance for civilian victims of the uprising, observed on October 2, and supported the creation of a memorial space at Warsaw's Insurgents Park.
She also remained engaged in public life, supporting the Solidarity movement during martial law in the 1980s and later speaking out on social and political issues.
In recent years, she advocated for democracy, women's rights and reconciliation between Poland and Germany.
At commemorations marking the 80th anniversary of the Warsaw Uprising, she called for Polish-German reconciliation, saying it was especially important in the face of new security threats.
"Let us forgive one another, as neighbours do; together we have the strength to stop Russia," she said.
