Oi Yoi Yoi is a 1963 oil painting by British painter Roger Hilton. Perhaps Hilton's best-known work, it is a free composition depicting a naked white woman. The central figure is abstracted, with simple black outlines drawn in charcoal of a featureless face, breasts and pubic triangle, and upraised arms. All four limbs are cut off at the edges of the frame. The white body contrasts with bold segments of background colour in yellow and red, blue and black. The work is inscribed on the back "Oi, yoi, yoi/Hilton/Dec 63".
