Ultimate Requiem is a series of comic books published by Marvel Comics. It takes place in the Ultimate Universe following the events of Ultimatum. The X-Men and Fantastic Four stories were published as one shots, while the Spider-Man story was published as a two-issue limited series. The books serve as an epilogue to each of the Ultimate Universe's three core titles, which were all canceled following Ultimatum. They are the last Ultimate Marvel comic books to be published before the imprint was relaunched as Ultimate Comics.
