Ushio Shinohara (篠原 有司男, Shinohara Ushio, born January 17, 1932), nicknamed “Gyū-chan”, is a Japanese contemporary painter, sculptor, and performance artist based in New York City. Best known for his vigorously painted, large-scale and dynamic Boxing Painting series, Shinohara makes use of embodied gestures, appropriation and assemblage, iconographies of mass culture and traditional arts, and vivid tones in his diverse, multidisciplinary practice.

A founding member of the short-lived, avant-garde collective Neo-Dada Organizers, Shinohara spent the early years of his life in Tokyo before moving to New York City in 1969, where he continues to live and work. Having grown up in Japan through a time of rapid political change, social upheaval, and increasing Americanization and modernization in the wake of the American occupation, Shinohara's work was shaped by and responsive to the clashing forces in his midst. His energetic confrontations with conventions of both traditional and contemporary artistic canons are filtered through a pop sensibility and an understanding of art-making as a series of ephemeral gestures rather than a results-based process.

His work has been exhibited internationally at institutions including the Hara Museum of Contemporary Art, Centre Georges Pompidou, the Guggenheim Museum SoHo, National Museum of Modern Art, Tokyo, National Museum of Modern Art, Kyoto, Leo Castelli Gallery, Museum of Contemporary Art, Los Angeles and the Japan Society. Shinohara and his wife, Noriko, are the subjects of a documentary film by Zachary Heinzerling called Cutie and the Boxer (2013).
