Seth, Canadian author and illustrator
Gregory Gallant (born September 16, 1962), better known by his pen name Seth, is a Canadian cartoonist. He is best known for his series Palookaville and his mock-autobiographical graphic novel It's a Good Life, If You Don't Weaken (1996).

Seth draws in a style influenced by the classic cartoonists of The New Yorker. His work is highly nostalgic, especially for the early-to-mid-20th Century period, and of Southern Ontario. His work also shows a great depth and breadth of knowledge of the history of comics and cartooning.
