Katie Morag is the title character of a series of children's picture books written and illustrated by Mairi Hedderwick. The gentle stories have been praised for their good humour, strong sense of place, and the feisty and independent (sometimes even "thrawn") character of Katie herself. The books are set on the fictional Isle of Struay, off the west coast of Scotland. Katie Morag lives close to the jetty above the island's only shop, where her mother is the postmistress and her father runs the general store.
