Ch'p is a member of the Green Lantern Corps in the DC Comics Universe. An extraterrestrial, he resembles an anthropomorphic rodent, such as a squirrel or chipmunk. He was created by Paul Kupperberg and Don Newton.
Ch'p's early history was recounted in Green Lantern Corps #203. A native of the planet H'lven, he participated in the defense of his homeworld from an invasion by the Crabster army of Doctor Ub'x. He was captured and sentenced to death, but one of the Guardians of the Universe came secretly to induct him into the Corps with the power ring of his predecessor, who had fallen attempting to stop the invasion. Using the ring, Ch'p was able to defeat Doctor Ub'x and free his world. Shortly afterward he travelled to Oa where he was instructed by Kilowog in the same group of recruits as Hal Jordan. Ch'p went on to become the Green Lantern of sector 1014, and became good friends with Jordan, Mogo, Salaak and other members of the Green Lantern Corps. Ch'p maintained a secret identity on H'lven until he married his longtime girlfriend M'nn'e. While not serving the Guardians on Oa, Ch'p defended H'lven from various threats, many of them engineered by his old nemesis Doctor Ub'x.
