Although the report didn't give a reason, fans and news outlets have speculated that the delay was to avoid competing with Avengers: Doomsday, Dune: Part III, and Ice Age 6, which are all set to hit cinemas in December 2026.
Fans have expressed disappointment at the delay, with one writing on X: "Another delay? At this point my kids will be showing Shrek 5 to their kids."
The first film, released in 2001, followed the story of an ogre who wants nothing more than to be left alone, but ends up on a quest to rescue a princess trapped in a tower.
Along the way, he gets help from a ragtag bunch of misfits, including a chatty donkey and, later, a boot-wearing cat.
It was a huge hit for DreamWorks, making $487m (£362m) worldwide at the box office.
The studio then went on to bring back the characters again and again for three more movies.
Number five will actually be the seventh film in the wider franchise, which includes two spin-off films - Puss In Boots and Puss In Boots: The Last Wish.
