Publication history of Marvel Comics crossover events

Throughout its history of publications, Marvel Comics has produced many inter-company crossover stories combining characters from different series. The following is a list of crossover events involving superheroes and characters from other series.

• "Event": (main story starts and ends in core limited series and side stories runs in multiple books)
• "Crossover": (main story starts and ends in a single or multiple ongoing books and side stories run in single or multiple books or main story can start and end with bookends and continue in multiple one-shots or ongoing books)
• "Limited Series": (main story starts and ends in single limited issue book)
• "One-Shot": (main story start and end in a single or multiple book)

Secret Wars was the first modern Marvel event where a separate limited series was launched, with other tie-ins following it. After its release, Marvel started having annual crossover events where a mini-series was established for the event, which impacted most Marvel comic books.

The Infinity Trilogy is a three-event arc about the Infinity Gems. Part 2 (Infinity War) and Part 3 (Infinity Crusade) deal with the fallout of the Infinity Gauntlet: the creation of separate parts of cosmic hero Adam Warlock, Goddess, and Magus.

As X-Men popularity grew in the 1980s, Marvel started doing crossovers between X-Men books, usually dubbed X-Overs.
