Jonathan Barnbrook (born 1966), is a British graphic designer, film maker and typographer. He trained at Saint Martins School of art and at the Royal College of art, both in London.
Barnbrook designed the cover artwork of David Bowie’s 2002 album Heathen, where he used his 'Priori' typeface for the first type. He also designed the cover for Bowie’s Reality album and the controversial cover for The Next Day.

A recurring theme of Barnbrook's graphic design is the series of personal responses to political events, which often follow or develop detournement methods. He describes as a major influence to his work "an inner anger which is a response to all the unfairness that is in this world". He has stated his ambition to use "design as a weapon for social change".
