Barbara Nowacka (b. 1975 in Warsaw) is a feminist, politician and left-wing activist. She holds an MBA and is an IT specialist by education. She is Chancellor of the Polish-Japanese Academy of Information Technology in Warsaw.

Nowacka is co-chair of the “Twój Ruch” Party, a member of the Women’s Congress National Council, and chair of the progressive association “Initiative Poland”.

She is also a co-founder and deputy chair of the Izabela Jaruga-Nowacka Foundation, an organization which aims to promote equality, social justice and social inclusion.

Nowacka headed the election committee for the “United Left” coalition during the 2015 Polish parliamentary election.

In 2016 she organized and chaired the “Save women” initiative, a civil bill which aimed to liberalise abortion laws in Poland. In October 2016, in response to an attempt by the political right to implement a total ban on abortion, Nowacka became a leading figure in the “Czarny Protest” action, a massive nationwide demonstration which ultimately succeeded in forcing the political right to back down. For her role in “Czarny Protest”, Nowacka was ranked one of the Top 100 Global Thinkers of 2016 by Foreign Policy magazine.
