Starlog was a monthly science fiction magazine that was created in 1976 and focused primarily on Star Trek at its inception. Kerry O'Quinn and Norman Jacobs were its creators and it was published by Starlog Group, Inc. in August 1976. Starlog was one of the first publications to report on the development of the first Star Wars movie, and it followed the development of what was to eventually become Star Trek: The Motion Picture (1979).

Starlog was born out of the Star Trek fandom craze, but also was inspired by the success of the magazine Cinefantastique which was the model of Star Trek and Star Wars coverage. Starlog, though it called itself a science fiction magazine, actually contained no fiction. The primary focus of the magazine, besides the fact that it was mostly based on Star Trek fandom, was the making of science fiction media - books, films, and television series - and the work that went into these creations. The magazine examined the form of science fiction and used interviews and features with artists and writers as its foundation.
