Monika Sosnowska (born 7 May 1972 in Ryki) is a Polish installation artist. In 2003 she received the Bâloise Prize at Art Basel as well as the Polityka's Passport award given by Poland’s most prestigious weekly.
Sosnowska studied at the Painting Department of the University of Fine Arts in Poznań (1993–1998), and the Rijksakademie van beeldende kunsten in Amsterdam (1999–2000). During her final years at the Poznań academy, she found that the "painting started to escape her canvas." She began to create works that played with both two-dimensional painting and three-dimensional space, finally giving up on canvas altogether and instead using space itself as a sort of 3D painting.
Sosnowska treats space as a medium for her works, always designing projects to fit into a specific space. Often she modifies pre-existent architecture, transforming physical space into mental space and playing with the viewer’s perceptions. She explained: "I am especially interested in the moments when architectural space begins to take on the characteristics of mental space." In 2004, she received the Ernst Schering Foundation academic scholarship. In 2012, she was nominated for the Hugo Boss Prize. She currently lives in Warsaw.
