Weasel (Jack Hammer) is a fictional character appearing in American comic books published by Marvel Comics. Weasel is a friend, sidekick, information broker and arms dealer for Deadpool. Weasel is perhaps Deadpool's best friend. However, because of his frequent mood swings and tenuous mental state, Deadpool still often abuses or mistreats him. Weasel has also displayed an opportunistic streak against his friend's interests on occasions.

T.J. Miller portrayed the character in the films Deadpool (2016) and Deadpool 2 (2018).
