Prison 42 is a prison that features in Marvel Comics.
After the Baxter Building was sent into the Negative Zone, the member of the Fantastic Four along with Lyja looked to find a way to return to Earth. It was then that Franklin Richards suggested that they use the portal at Prison 42. This saw the Thing break into the prison where they recruited the aid of the Tinkerer to help send them back to the positive-matter dimension. At first, Mason refused as he resented the heroes for sending him into the prison. However, upon seeing Franklin and Valeria Richards, he decided to aid them as the two children reminded him of his own grandchildren. (Secret Invasion: Fantastic Four v1 #3)
In the wake of World War Hulk, the only member of the Warbound that fell into S.H.I.E.L.D.s custody was Miek who was kept within the Negative Zone Prison where he was interrogation for information by Kate Waynesboro about his former teammates. (World War Hulk Aftersmash: Warbound v1 #2)
King Blastaar and his forces later laid siege to Prison 42 in an attempt to use it as a portal to invade Earth. During their attack, the wardens and guards fled but freed the prisoners whilst shutting down the machines that dampened their powers. The freed prisoners then attempted to defend the prison as they had no way of escaping as the fleeing guards had closed the portal behind them. Star-Lord was sent as a messenger to the prison's defenders to negotiate their surrender where he allied with Jack Flag to prevent the Negative Zone attackers from overrunning the facility. (Guardians of the Galaxy v2 #9) Despite the attempt, the prison population quickly fell in line with most surrendering to Blastaar with those resisting being killed except for those that escaped with the Guardians of the Galaxy. Blastaar then attempted to have Skeleton Ki to use his abilities to open the doorway to Earth but that world's heroes were warned to keep the portal closed. (Guardians of the Galaxy v2 #10)

In other media
- In The Avengers: Earth's Mightiest Heroes, Prison 42 was created by Tony Stark, Hank Pym and Reed Richards with it being situated in the Negative Zone. Due to Loki's actions, Earth's various supervillains were broken free from containment and the prisons no longer capable of holding them. This lead to Stark, Pym and Richards sifting through various designs on where to contain the freed supervillains. Prison 42 was the 42nd idea that they had which was built in the Negative Zone and staffed by various Ultron synthoids to keep the prisoners contained.
- In Marvel: Ultimate Alliance 2, Prison 42 was created in the Negative Zone by the supporters of the Registration Act as a place where unregistered heroes and supervillains were kept imprisoned. The villains were kept contained through the use of nanites that mind-controlled them. It was the site where the nanites evolved sentience to become the Fold where they attempted to take over the prison. Nick Fury attempted to stop the spread of the Fold to Earth by self-destructing Prison 42 but failed in this goal.
