G.I. Joe and the Transformers (toyline)
| This article is about the toy line homaging various crossovers between the Transformers and G.I. Joe brands. For 1986 comic crossover by Marvel Comics, see G.I. Joe and the Transformers (comic). For other crossovers with G.I. Joe, see G.I. Joe crossovers (disambiguation). |

G.I. Joe and the Transformers is the name under which crossovers in toy form between Transformers and the G.I. Joe franchise are sold.
Initially, the "toy line" was made up entirely of annually released sets available exclusively at the Hasbro Toy Shop booth at San Diego Comic-Con, and subsequently at the Hasbro Toy Shop website, with the themes of the sets and the packaging design meant to commemorate the eponymous G.I. Joe and the Transformers comic book mini-series from Marvel Comics, including a continuation of the series' numbering. Those sets consisted entirely of redecos of figures and vehicles taken from the G.I. Joe line, with non-transforming G.I. Joe vehicles made to resemble Transformers characters.
Later, Fun Publications also released several crossover sets that were exclusively available through both the Transformers Collectors' Club store and the G.I. Joe Collectors' Club store under the same name. Those sets commemorated instances of crossovers between the two brands in season 3 of the original Transformers television series, and later also the issues of the Marvel G.I. Joe comic that served as a prelude to the Generation 2 comic, again using mostly redecos of G.I. Joe figures and vehicles but this time also including redecos of actual Transformers figures.
Even though the annual Hasbro Toy Shop/San Diego Comic-Con sets supposedly ended in 2013 with a set named "The Epic Conclusion!", 2016 saw the release of another set.
