Sidney Arnold Barron (June 13, 1917 in Toronto – April 29, 2006 in Victoria, British Columbia) was a Canadian editorial cartoonist and artist.

His cartoons were satirical takes on social mores, and often contained a biplane towing a banner, and a bored-looking cat, holding a card bearing a wry comment.

During the First World War, Sid Barron's mother, Daisy Hilda Wormald, moved from England to her married sister Florence's household in Toronto[1] after becoming pregnant by a Belgian soldier billeted with her parents.

[4] After graduating from high school, Barron found work as a sign painter and commercial illustrator during the Great Depression, producing, among other things, schedule cards for Union Steamships.

Journalist Brenda Gough characterized his work as "relatively mild yet satirically insightful topical cartoons of social mores and suburbia [that] utilized a clear line and elegant, unexaggerated figures placed in extremely cluttered backgrounds full of sight gags and signs.

[1] After the National Archives of Canada and the Glenbow Museum bought many of his original cartoons, he was able to retire as a cartoonist, and he and Jesi travelled for several years.
