Guthrie Edward Melville "Gus" Wilson MC OBE (8 November 1914 – 9 December 1984) was a New Zealand and Australian novelist and educator.
His first teaching job was at Central Primary School, Palmerston North, in 1936, which he later described as a "living death"; in Easter 1937 he went to Marlborough College.
In 1954 he missed out on the position of rector (headmaster) at the school, because of controversy about the "pornography" and "foul language" in his first novel, Brave Company (led by the local MP Blair Tennent).
He was appointed an Officer of the Order of the British Empire in the 1977 Silver Jubilee and Queen's Birthday Honours for Australia for his services to Education.
His first novel, Brave Company, was an international best-seller first published in the United States, and was controversial for its explicit language.
