Peter D. Brookes (born 28 September 1943) is a English cartoonist who has produced work for numerous publications, including Radio Times, New Society, New Statesman, The Spectator and most notably The Times, for which he is the leader-page cartoonist.
Brookes was born in Liverpool, the son of an RAF Officer. After leaving school, he began training to be an RAF pilot but did not fit in well with the military lifestyle. In 1965, he undertook a year's foundation course in art in Manchester, continuing his studies at the Central School of Art (now the Central Saint Martins College of Art and Design) in London.
Brookes has worked for a range of publications, including New Society (which used one of his cartoons as a cover illustration in 1968) and the Radio Times. He had a short stint as a political cartoonist for the New Statesman, before returning to academia and lecturing at the Central School of Art and the Royal College of Art. For a time he worked as cover artist for the Spectator but, in 1992, he moved to the Times, as its leader-page cartoonist.
