A pilot for the show, which is based on a Douglas Adams novel, aired last December.
The programme's star Stephen Mangan has now confirmed that the BBC has asked for some new episodes.
Writing on his Twitter page, he said: "Dirk Gently gets recommissioned! BBC Four have asked for 3 x one hours... No news yet on what they will be about/which bits of the books will be there/when they will be on. (sic)"
Mangan also joked: "That's the good news, the bad news is that Gok Wan will be playing Dirk and Kay Burley will be Richard MacDuff."
Mangan had previously claimed that he would be "heartbroken" if the show wasn't renewed.
Dirk Gently, which follows Mangan's character as he uses unusual methods to solve crimes, is written by Misfits scribe Howard Overman.
