Oksana Shachko (31 January 1987, Khmelnytskyi, Ukraine — 23 July 2018, Paris, France) was a Ukrainian artist, feminist activist, and revolutionary. From an early age, she studied at the Nikosha School, where she specialized in Orthodox icon painting — a discipline traditionally reserved for adults.

As a child, she participated in numerous group exhibitions organized by the school. At the age of ten (1997), she received her first commission to create church frescoes in Khmelnytskyi and, at that time, aspired to become a nun. However, after graduating from art school, she chose a different path and enrolled at Khmelnytskyi Free University.

During her university years, she began studying philosophy, which profoundly transformed her worldview. For ideological reasons, Shachko stopped painting icons, though she continued to develop her artistic practice.

From 2003 to 2009, she was a co-founder and active participant as an artist in the women's youth organization New Ethic. In 2005, together with friends, she co-founded the communist youth organization Centre of Youth Initiative, with a focus on fostering collective discussion of socially important issues and encouraging civic engagement.

In 2008, she took part in the creation of the feminist group FEMEN in Khmelnytskyi, aimed at confronting corrupt capitalist and patriarchal political systems in Ukraine, Belarus, and Russia. Within a year, the group relocated to Kyiv. Between 2011 and 2014, she worked on the documentary Je suis Femen, directed by Alain Margot.

In 2015, she participated in the group exhibition 8 ± 2 at Galerie Mansart in Paris. In 2016, she presented her first solo exhibition ICONOCLASTE in Paris, and her works entered private collections.

This was followed by numerous other solo and group exhibitions, including in Paris, Brussels, and Copenhagen. In 2017, she enrolled at the École des Beaux-Arts in Paris. Her last exhibition took place in Paris in June 2018. Her icons, including a triptych of Orthodox crosses transforming into Kalashnikovs, were then exhibited as part of the "Talking about a Revolution" exhibition dedicated to the revolution and May 68, at the 22 Visconti gallery.

Oksana Shachko died on 23 July 2018 in her Paris apartment at the age of 31. She left a note with the message: "You are fake."
