Spider-Punk (Hobart Brown) is a superhero appearing in American comic books published by Marvel Comics. He is an alternate version of Hobie Brown and Spider-Man. His antagonists include President Norman Osborn, V.E.N.O.M., and the Inheritors.

Hobie Brown / Spider-Punk made his film debut in Spider-Man: Across the Spider-Verse, voiced by Daniel Kaluuya, and is set to return in Spider-Man: Beyond the Spider-Verse.

Spider-Punk was created by writer Dan Slott and artist Olivier Coipel. The idea of a punk Spider-Man emerged when Coipel proposed the look for Spider-UK. Slott rejected the look as wrong for a member of the Captain Britain corps but used it to develop a new character that would be "all punk".

Spider-Punk first appeared in The Amazing Spider-Man #10 (January 2015), during the "Spider-Verse" storyline. He again appeared during the "Spider-Geddon" storyline in 2018. In the stories, he interacts with Superior Spider-Man, Pavitr Prabhakar, Miles Morales, and Spider-Man Noir.

In 2022, he appeared in his first solo miniseries, written by Cody Ziglar. The story includes references punk variants of many Marvel characters, as well as songs and imagery of punk rock and hardcore punk bands such as MC5, Ramones, Dead Kennedys, and Misfits.

In the "Spider-Verse" storyline, the Earth-138 version of Spider-Man is revealed to be Hobart Brown, originally operating as Spider-Punk. He is a homeless teenager who was transformed by a spider that was irradiated by toxic waste dumped by President Norman Osborn. He becomes the punk rock-inspired Spider-Man, leading the downtrodden people of New York against Osborn's V.E.N.O.M. troops. Spider-Punk manages to kill Osborn during a riot by bashing him with his guitar. After Osborn's death, Spider-Punk publicly reveals his identity to the crowd present, who view him as their savior. Spider-Punk is later recruited by Superior Spider-Man to join an army of Spider-Men.

During the "Spider-Geddon" storyline, Spider-Punk is shown to be fighting Thunderstrike while the other Web Warriors are dismantling Loomworld. Spider-Punk (who is starting to call himself Spider-Man) takes down Thunderstrike, who is killed by Kang the Conqueror shortly afterward. Spider-Punk escapes from Kang and asks for a tape from Captain Anarchy, who is busy fighting the Annihilation Wave. When Kang's Spider-Punk dolls catch up to Spider-Punk, they get into a fight with the Annihilation Wave, with one of them eating Captain Anarchy's tape. As Captain Anarchy holds Kang off, Spider-Punk swings away.

Meeting up with Robbie Banner, Hobie tries to convince him to help while reminding him of how he helped in battles against the U-Foes, the Universal Church of Truth, and Hydra. When Kang catches up again, Robbie becomes the Hulk to attack Kang. After Kang disappears, Spider-Girl shows up and states that something big is coming, and Spider-Punk agrees to go with her. Spider-Punk later visits an unnamed reality and saves the Norman Osborn version of Spider-Man from the collapsing Oscorp Tower. In a flashback to seven months prior, Spider-Punk assists Spider-Girl, Pavitr Prabhakar, Spider-UK, and Karn, who have been keeping surveillance on the Inheritors.
