Kempton Cannon Bunton (14 June 1904 – 1976) was a disabled British pensioner who confessed to stealing Francisco Goya's painting Portrait of the Duke of Wellington from the National Gallery in London in 1961. The theft of the painting was the subject of the October 2015 BBC Radio 4 drama Kempton and the Duke, and the 2020 movie The Duke. A National Archives file released in 2012 revealed that Bunton's son, John, had confessed to the theft in 1969.
