What Is Prince George’s Last Name?

Prince George might be the future King of England but, to his classmates, he’s just an ordinary five-year-old with an ordinary last name — sort of. Thanks to deep-rooted royal name rules, Prince George and his siblings must follow certain protocols when using a surname or going by anything but their respective titles. What is Prince George’s last name? Find out, below.

Prince George’s last name

Despite their family heritage, Prince William and Kate Middleton try as hard as they can to give their children a normal life and help them fit in with other kids their age by using their last name versus a royal title in certain settings.

Because Prince George has His Royal Highness tacked onto the front of his official royal title, he doesn’t actually require a last name. However, when he needs one — such as, at school — he has a couple of options to choose from.

When using a last name, the young prince most likely goes by George Cambridge as a nod to his immediate family’s official royal title and house name. However, he could also choose the royal family’s surname, Mountbatten-Windsor, which applies to all decedents of Queen Elizabeth II and Prince Philip.

Prince George’s full name

We know him casually as Prince George, but his full name is actually George Alexander Louis. In the royal family, names are often selected based on past members. It is likely that Prince William and Kate Middleton came up with George after the queen’s father. However, they have quite the story for how it became their son’s first name.

The Duke and Duchess of Cambridge allegedly placed pieces of paper on the floor with baby names written down. Then, they had their dog, Lupo sniff them out. The royal pup allegedly stopped on the name “George” and that was that.

Prince George’s royal title

Since Prince William and Kate Middleton are the Duke and Duchess of Cambridge, all three of their children have Cambridge in their royal title. So, Prince George is His Royal Highness Prince George of Cambridge.

That said, Prince George’s title will change quite a bit in his life — even in his adolescent years. Since his father’s title will likely change to Prince of Wales in the near future, Prince George could become Prince George of Wales before he reaches majority.

Will Prince George be Prince of Wales?

Like his grandfather and (most-likely) his father, Prince George will probably hold the Prince of Wales title one day. Reserved for the British heir, Prince of Wales is one of the highest ranking titles in the royal family and typically accompanied by a special dukedom, Duke of Cornwall.

Will Prince George become Duke of Cambridge?

Prince George most-likely won’t become the Duke of Cambridge, like his father. If his father becomes king before he marries (which is likely), Prince William will likely make his son Prince of Wales and Duke of Cornwall — the two titles held by the British heir — instead.
