National Geographic Kids (often nicknamed to Nat Geo Kids) is a children's magazine published by the National Geographic Society. Its first issue was printed in September 1975 under the original title National Geographic World (which itself replaced the much older National Geographic School Bulletin, published weekly during the school year from 1919 to 1975; currently National Geographic produces a separate magazine for classroom use called "National Geographic Explorer," in four separate editions for different grades).

The magazine was published for twenty-six years as National Geographic World, until the title of the magazine was changed in 2002 to National Geographic Kids. In a broad sense, the publication is a version of National Geographic, the flagship magazine of the National Geographic Society, that is intended for children.
