Stanley McMurtry MBE (born 4 May 1936), often referred to as Mac, is a British cartoonist. McMurtry is perhaps most famous for his work, since 1970, for British newspaper The Daily Mail.
McMurtry's work is essentially apolitical and he views his role as making "dreary news copy of the daily paper brighter, by putting in a laugh".
Mac was granted an MBE in the 2003 New Year's honours list for "services to the newspaper industry".
In most of his daily cartoons, Mac includes a small portrait of his wife hidden within the picture. However, he does not include her when the cartoon makes a political statement, or when it depicts a tragedy.
