Antonietta Grassi (b. 1965) is a Montreal-based artist whose abstract paintings investigate the intersections of textiles, technology, and modernist abstraction through layered geometries and meticulously rendered, threadlike lines. Her work evokes intricate, woven-like surfaces that reference early computing, analog machines, and the often-overlooked contributions of women to technological innovation, while engaging the formal history of modernist abstraction.

Grassi’s paintings are held in private and major public collections including the Musée national des beaux-arts du Québec, the Musée d’art contemporain de Baie-Saint-Paul, the Archives of Ontario, the Canadian Embassies in Dubai and Tunisia, the Quebec Delegation in Tokyo, the Boston Public Library, Rutgers University (CINJ), McGill University, and the Conseil des arts et des lettres du Québec. Her work has been exhibited at Expo Dubai, the Katonah Museum of Art, the Armory Show, and the Musée national des beaux-arts du Québec, among others.

A 2024 Guggenheim Fellow and the recipient of numerous awards and residencies, Grassi holds an MFA from L'UQAM and a BFA from Concordia University. She has completed several public art commissions, and her work will be the subject of a solo exhibition at the Musée de Sherbrooke, Québec in 2026.
