Prince Louis’s Adorable Nickname from His Older Siblings

Updated: Jan. 05, 2023

Prince Louis's nickname is the very definition of royal cuteness—and it's just the latest in a long line of sweet royal monikers

Since the dawn of time, siblings have given each other childhood nicknames. Sometimes these names arise because little ones can’t pronounce a brother’s or sister’s name properly. In other instances, they come from silly family situations. Even the Cambridge kiddos have nicknames for one another. Prince Louis, in particular, has been bestowed with an especially adorable moniker by his older siblings, Prince George and Princess Charlotte.

The youngest of Prince William and Kate Middleton‘s children, Prince Louis made quite an impression on the world with his 4-year-old antics during Queen Elizabeth’s Platinum Jubilee. While all the next-generation royals have captured our attention, the baby of the family became a real media darling that weekend. We all wanted to know more about the cutie pie who simply could not sit still during the royal events. After all, cheeky kids in the royal family tree are often the most relatable to us common folk, and nicknames and other personal anecdotes endear them to us even more.

What is Prince Louis’s nickname?

When Prince Louis and his famous siblings are just kicking around the house, they have taken to calling him “Lou Lou.” And this isn’t a new nickname. Royal sources recently revealed that Prince George and Princess Charlotte have been referring to Louis as Lou Lou since he was a baby. It’s so sweet and endearing, right? And it rolls off the tongue a lot more easily than His Royal Highness Prince Louis Arthur Charles of Cambridge, which is his full name and title. For those keeping count, this cutie is fifth in the line of succession to the British throne. That means Prince Charles, Prince William, Prince George and Princess Charlotte come before him.

Do Prince George and Princess Charlotte have nicknames?

Not to be left out of the family fun, Prince George and Princess Charlotte do, indeed, also have nicknames. Unfortunately, as the youngest sibling, Prince Louis didn’t have a hand in choosing the monikers for them. At school, Prince George’s classmates reportedly call him PG, and some friends also call him Tips, as a reference to the popular British tea brand PG Tips.

As for Princess Charlotte, she is often called Lottie by friends and family, including her parents, as a way of shortening her name. This makes perfect sense to us because the other popular option for shortening Charlotte is Charlie. Considering her grandfather is Prince Charles, that could make family gatherings all sorts of confusing.

According to royal watchers, Prince William also refers to his daughter as Mignonette. In French, the word mignon means sweet and delicate.

What are some other royal nicknames?

It’s not only the royal children who have nicknames. Many of the adults also use special monikers and terms of endearment for their loved ones—including Queen Elizabeth. For starters, Prince George calls her Gan-Gan. When he was just a toddler learning to talk, the future king couldn’t say the words granny or grandmother. So, Gan-Gan it was. For his part, Prince William simply calls the monarch Gran. We have a feeling the Queen doesn’t mind the variety of nicknames from her grandchildren and great-grandchildren.

But wait—those aren’t the Queen’s only nicknames. Her late husband, Prince Philip, affectionately called her Cabbage. Yes, Cabbage. This unusual nickname may have its roots in the French term mon petit chou, which is a way of saying “my darling” but translates to “my little cabbage” in English. And Elizabeth’s parents referred to her as Lilibet as a child, which is where Harry and Meghan’s daughter gets her name.

As for Prince William, it is said that Princess Diana bestowed the nickname “Wombat” on him as a child during a tour of Australia. The quirky name stuck with him throughout all his younger years. More recently, Prince William’s couple nickname from college has been reported on.
