What is the royal baby boy’s title?
Understanding royal titles can be tricky because they can hold more than one – especially after they’re married.
Kate and Wills’ latest addition holds the formal title: His Royal Highness Prince Louis of the United Kingdom of Great Britain and Northern Ireland.
This is the baby’s official title – but he will have others.
Historian Marlene Koenig told Town & Country that royal children’s titles are styled differently if they are also the children of a duke.
This means that because the new prince’s parents are the Duke and Duchess of Cambridge, he will also have the title of His Royal Highness Prince Louis of Cambridge.
Kensington Palace confirmed that this is what the royal tot will be known as when they revealed Louis’ name on April 27.
They tweeted: “The Duke and Duchess of Cambridge are delighted to announce that they have named their son Louis Arthur Charles.
“The baby will be known as His Royal Highness Prince Louis of Cambridge.”
If the baby had been a girl, her formal title would have been, Her Royal Highness Princess (Name) of the United Kingdom of Great Britain and Northern Ireland.

Why is Prince Louis technically a commoner?
It does get more confusing.
Marlene also said that the new royal has technically been born a commoner.
She added: “It sounds complicated, but in the UK, the only people who are not commoners are the Sovereign and peers of the realm, [people with titles like] Duke, Marquess, Earl, Viscount, and Baron.”
This means Prince Harry is technically a commoner too – until he marries Meghan Markle in May.
The Queen then has the option to grant Harry and Meghan new titles after they are wed.
