Martin Rowson (born 15 February 1959) is a British editorial cartoonist and writer. His genre is political satire and his style is scathing and graphic. He characterizes his work as "visual journalism". His cartoons appear frequently in The Guardian and the Daily Mirror. He also contributes freelance cartoons to other publications, such as Tribune, Index on Censorship and the Morning Star.
Rowson was adopted as a child, and educated at the independent Merchant Taylors' School in Northwood in north-west London, followed by Pembroke College, Cambridge where he read English Literature.
Rowson's books include graphic adaptations of The Waste Land and Tristram Shandy. Snatches, his novel, was published in 2006 (). It is a comic journey through history, focusing on the "stories of the worst decisions the human race has ever made". Stuff (2007), his next novel, is part autobiography, part history of his family and upbringing. He also drew original cartoons for the title sequence of the film Pride and Prejudice and Zombies.
In 2008 he published The Dog Allusion: Gods, Pets and How to Be Human, arguing that religion is a complete waste of time and money — much like keeping pets. (The title is itself an allusion to the Richard Dawkins book The God Delusion.) In 2014 'The Coalition Book' containing a collection of cartoons, and a written account, of the four years of the coalition government was published by Self Made Hero. He is an Honorary Associate of the National Secular Society and a distinguished supporter and board member of the British Humanist Association.
