Joanna Narutowicz née Billewicz (Lithuanian: Joana Bilevičiūtė-Narutavičienė; 21 March 1868 – 19 February 1948) was a Polish-Lithuanian educational activist and the last owner of the Brėvikiai Manor [lt] (Lithuania).

She married Stanisław Narutowicz, a signatory of the Act of Independence of Lithuania, with whom she ran several cultural facilities.

Her siblings included educator Sofija Bilevičiūtė-Zubovienė and chemical engineer Konrad Billewicz [pl].

[4] She found herself in the circle of students gathered around the Walka Klas [pl] magazine published in Geneva by Stanisław Mendelson.

[5] The circle was called "Olympus" and was formed by young people with socialist views: Zofia Poznańska, Feliks Daszyński [pl], Stanisława Popławska and her husband, Maria Kozłowska, Aleksander Tupalski, Gabriel Narutowicz, Barbora Burbaitė, Teodor Kodis, Aleksander Dębski [pl] and Józefa Krzyżanowska.

[1] The couple briefly lived in Warsaw and Vilnius before moving to her husband's estate in Brėvikiai [lt].

The school building was not affected, but local parents suffered financial losses and could not afford to pay for their daughters' education.

A local noble agreed to donate a good portion of the tuition fees, while Narutowicz covered the rest from personal funds thus saving the school.
