Nadia Khiari (Arabic: نادية خياري; born 21 May 1973) is a Tunisian cartoonist, painter, graffiti artist and art teacher.

She is best known for her chronicles and cartoon collections about the Arab Springs,[1] particularly for her character 'Willis from Tunis', dubbed the "Cat of the Revolution" in some sources.

[1] Apart from social media, Khiari's work has been published in magazines such as Siné Mensuel, Courrier International and Zelium.

In January 2011, she started the page Willis from Tunis[4] on Facebook to air her feelings about the Arab Spring, which attracted over 56,000 followers in August 2021.

[3] Due to the former regime's strict policies of censorship and to avoid being thrown into prison, she was careful to "learn to trick, to suggest rather than to speak".
