Transformers: Generation One was a Dreamwave Productions comic book series, consisting of two six-issue limited series and an ongoing title. Within the same continuity were three other Dreamwave series: a series of character profiles entitled Transformers: More Than Meets the Eye, a prequel miniseries entitled, Transformers: Micromasters and another prequel ongoing miniseries called Transformers: The War Within. In addition, a single story was part of the Transformers Summer Special. All ongoing series were cancelled in 2005 due to Dreamwave's bankruptcy, leaving their plotlines unresolved.

Transformers: Generation 1 is a toy line from 1984 to 1990, produced by Hasbro and Takara Tomy. It was a line of toy robots that could change into an alternate form by moving parts into other places, and it was the first line of toys produced for the successful Transformers toy and entertainment franchise. The line was originally called The Transformers, with "Generation 1" originating as a term coined by fans of the toys when the Transformers: Generation 2 toy line was released in 1992. Hasbro eventually adopted the term "Generation 1" to refer to any toy produced in that era.
