He will take the reins from current co-writer Rick Remender on the Marvel Comics series from issue #23.
Following the announcement at Marvel's Next Big Thing press conference, Bunn said that his first arc would deal with Flash Thompson's decision to become a full-time hero, and the backlash he receives from the superhero community.
He revealed that the title would not be connected to his current, symbiote-featuring Captain America & Hawkeye arc.
Bunn recently completed the Fearless limited series for Marvel and has joined Wolverine as the title's writer.
He is best known as the co-creator of Oni Press's The Sixth Gun.
Venom #22 will be released in August.
