Iakovos "Jake" Chapman (born 1966) and Konstantinos "Dinos" Chapman (born 1962) are English visual artists, often known as the Chapman Brothers, who work together as a collaborative sibling duo. Their subject matter is often deliberately shocking, including, in 2008, a series of works that appropriated original watercolours by Adolf Hitler. Nominated for the annual Turner Prize, the two have won critical acclaim. Their works are held in numerous public and private collections.
