And his favourite is one of the scariest and most well known, the Tyrannosaurus Rex!
Prince George's Mum, Kate Middleton, revealed to children which dinosaur was his favourite during a visit to the Natural History Museum.
She said "George loves the T Rex because it's the noisiest and the scariest."
Kate was visiting the museum for a special children's tea party being held to say goodbye to Dippy the Dinosaur.
Dippy is the museum's most easily recognised exhibit, a massive 21.3m model of a Diplodocus skeleton and was presented to the museum more than 115 years ago!
It is being packed up and sent on a tour of the UK, so every piece must be labelled and packed away. A job that's about as big as dippy is!
We all love dinosaurs and Prince George is no exception.
