Mouse Guard is a comic book by David Petersen, published by Archaia Studios Press. It mostly features the Mouse Guard order, an organisation working to protect all mice, and is set in a medieval-level world, featuring several outspread cities, fortresses and villages.

Instead of combat and direct action amongst mice, the stories usually moves around pathfinding, border-watching (mostly against neighbouring weasels and other predators), guiding, weather-watching, averting predators, road patrol and escort and making the lands safe for all mice.
