Aaron Blabey (born January 1, 1974) is an Australian author of children's books and former actor in television and film roles throughout the 1990s and 2000s. From the mid-2000s, Blabey turned his attention away from acting and towards painting and created six separate solo exhibitions across Australia between 2004 and 2006.

He is the creator of three best-selling children's series; Pig the Pug – a picture book series about a rude, selfish, mean-spirited little dog; The Bad Guys – a New York Times #1 bestselling graphic novel series for junior readers about a gang of scary-looking animals trying to change their bad reputations; and Thelma the Unicorn – a second picture book series about a plain little pony who pretends to be a unicorn.

He married an Australian actress and speech pathologist Kirstie Hutton in 2000.
