Harry and His Bucket Full of Dinosaurs is a series of children's books written and drawn by Ian Whybrow and Adrian Reynolds. The series is about a 5-year-old boy named Harry, who has a bucket full of six dinosaurs (seven in the books) named Taury, Trike, Patsy, Pterence, Sid, and Steggy. In the books the dinosaurs talk to Harry but seem to be toys to the other characters. The other main characters are Mum, Nana, Harry's best friend Charlie and Harry's sister Sam. A major difference is that the book series includes an Anchisaurus while the TV series does not.

It was later adapted into a British-Canadian 104-episode animated television series of the same name, which premiered on Teletoon in Canada on March 28, 2005 and ended in 2008. It is a co-production between CCI Entertainment in Canada and Collingwood O'Hare Entertainment Ltd. in the United Kingdom, presented by CCI Releasing, in association with Discovery Kids Latin America, Teletoon (season 1), Treehouse TV (season 2), Cartoon Network, (season 1), Super RTL (season 1), Channel 5 Broadcasting Limited (season 2), and Playhouse Disney UK. In the TV series Harry plays with the dinosaurs by jumping into the bucket, which transports him to another world, called DinoWorld. Although the dinosaurs are toy-sized in the real world, within DinoWorld they become dinosaur-sized, while Harry retains his actual size. The TV episodes are available on DVD in two volumes.

Recently, it was announced that the show would have a series of apps for the iOS and Android platform and will include some interactive elements.In the US, Cartoon Network aired the series as part of its short-lived Tickle-U block. Reruns of the series aired on Qubo from June 30, 2012, to December 25, 2020.
