The Chief Weasel is the main antagonist of Kenneth Grahame's novel The Wind in the Willows. He is the leader of a rogue band of weasels living in the Wild Wood, and thus inspires fear amongst the local riverbankers. When Mole ventures into the Wild Wood, the weasels and their Chief spy on him menacingly, and scare Mole witless. Later, the weasels and their Chief forcefully invade Toad Hall when Toad himself is being impeded in prison. The Chief declares Toad Hall his and has the weasels do his bidding. However, Toad breaks out of prison and rejoins his friends. Badger decides that they must get the Hall back but Toad underestimates his own courage and tries to march up to the weasels and demand the Hall back but they shoot at him to get him running off. Toad therefore joins Badger, Rat and Mole in an expedition to get the Hall back for Toad and they break in through an underground tunnel when the Chief Weasel is having a feast with the weasels. Toad and the others jump out of a trapdoor right into the dining room and scare the weasels senseless, making it easy for them to drive the weasels out of the place. The Chief Weasel is beaten senseless by Toad and is presumably later arrested.
