Sean Leahy (born 1958) is an Australian cartoonist working for the Courier Mail in Brisbane, Australia. He draws political cartoons for the paper, and also his own comic strip, Beyond the Black Stump, which is distributed in Australia, the United States and the United Kingdom.
In 1974, Sean Leahy began his cartooning career on the suburban weekly The Darling Advertiser while still in high school. One year later, his cartoons became a common feature of The West Australian, making him the youngest political cartoonist in Australia at a metropolitan daily.
Leahy was awarded a Queen Elizabeth II Jubilee Trust Award to study animation in the United States in 1982. When he was there, he spent time at Mike Jones Film Corporation in Minneapolis before returning to Perth.
In 1983, he left The West Australian and joined The Daily Sun, then The Courier-Mail in Brisbane.
Beyond The Black Stump 
Beginning in 1988, Leahy started the nationally-syndicated comic strip Beyond The Black Stump, which he writes and draws himself.
Leahy's cartoons continue to appear in more than 150 publications throughout the world via the Cartoonist's and Writer's Syndicate in New York. Major papers such as The Times and The International Herald-Tribune have printed his work.
Leahy traveled to the US and UK in 2004 for further study in animation as a recipient of a Churchill Fellowship.
Originals of his cartoons are included in private collections ranging from Steven Spielberg to the Vatican.
