Toy Story 4 will be a romcom, with less of a focus on the relationship between the characters and children.
Pixar studio president Jim Morris made the revelation in an interview to Spanish fan site Disney Latino, in which he talked about the future direction of the animated franchise.
"It will be a love story," he said. "It will be a romantic comedy.
"It will not put much focus on the interaction between the characters and children."
John Lasseter, who directed Toy Story and Toy Story 2, is returning to direct the new film, which is due for release on 16 June, 2017.
