Clifford the Big Red Dog is an animated children's television series which is a reboot to the book series of the same name written by Norman Bridwell, and the 2000 original series created by Deborah Forte and produced by Mike Young Productions, and is the third series in the franchise after the prequel spin-off Clifford's Puppy Days, which was also produced by Mike Young Productions.

In addition to being a reboot, it is also a sequel, because PBS lists it as being the third season.

Clifford is now voiced by Adam Sanders, replacing John Ritter in the role since his death in 2003.

It was released on December 6, 2019, on Amazon Prime Video, and premiered a day later on PBS Kids. The second part of season 1 was released on February 7, 2020. The executive producers of the show include Jennifer Oxley, best known for co-creating Peg + Cat, and Vince Commisso of 9 Story Media Group.

The series revolves around Emily Elizabeth Howard, a young girl who owns Clifford, a big red dog who can speak to her for the first time since the late 1980s-early 1990s direct-to-video series. Together the two friends explore their island home, Birdwell Island, and embark on adventures.

Jetta, Vaz, Charlie, T-Bone, Mac, and Cleo are all removed from the reboot, with Samantha, Jack, Pablo, Tucker and Bailey replacing all the classic characters. The Speckle Story was also removed in Season 3, and the show went straight to the next segment.
