The popular fantasy novel series ended with the seventh instalment, "Harry Potter and the Deathly Hallows".
Rowling spoke about the future of the series in a conversation with the "Today" show's Matt Lauer.
"I'm afraid I haven't been writing the next Harry Potter. Well, you know, I keep saying that I feel I've wrapped Harry's story up and you gotta know when to... Look, I've always, I have always said, 'Never say never'-well not, 'Never say never.' I've always said, I'm not gonna say 'I definitely won't' because I don't see why I should say that," Rowling told Lauer.
"See, now, I heard that answer and I thought there's hope," Lauer told her. "'So you're not saying 'no'!" Rowling said, laughing.
The film franchise, based on the book series, starred Daniel Radcliffe in titular role and had eight parts, with the final two being "Harry Potter and the Deathly Hallows- Part 1" and "Harry Potter and the Deathly Hallows- Part 2".
