Is Kate Middleton a Princess? How Her Royal Title Might Change Once Prince Charles Is King

With Queen Elizabeth II in her 90s, many have their eyes on how the royal family will change once Prince Charles is king. And, as it turns out, his ascension to the throne could change a lot — including Kate Middleton’s royal title. Because the duchess is married to the future heir apparent (aka, Prince William), she could receive a list of new royal titles when Prince Charles takes the throne.

Kate Middleton’s royal titles

An official royal title might not seem that important to us commoners, but in the royal family, it’s everything. Queen Elizabeth and the rest of the royal family use official titles to tell the difference between immediate family members — such as Prince William, Kate Middleton, and their children, aka the Cambridges. But, that’s not their sole (or most important) purpose.

Royal titles are a way to note one’s rank within the family, which often determines members’ roles, accomplishments, and sometimes even maturity. Case in point: In the royal family, the sons and grandsons of the monarch often receive a dukedom — the highest ranking title, aside from Her or His Majesty — upon marriage or majority. If someone if a duke in the royal family, you can almost guarantee they play a significant role (or are at least related to someone who does) within the family. And, if someone is a duchess, it means they likely married a duke.

On his wedding day, Queen Elizabeth II granted Prince William a royal dukedom. Which then granted his bride, Kate Middleton automatic duchess status. According to royal family rules, official titles typically get pass down through the male line. So, since Prince William is the Duke of Cambridge, that makes Kate Middleton the Duchess of Cambridge.

In addition to Duchess of Cambridge, Kate Middleton has a few other royal titles, which typically get used while traveling to different countries in the United Kingdom. Here are all of Kate Middleton’s royal titles:

Her Royal Highness Catherine, Duchess of Cambridge

Kate Middleton’s royal title most often used is Her Royal Highness Catherine, Duchess of Cambridge, or Her Royal Highness The Duchess of Cambridge. She received this official title on her wedding day to match her husband’s dukedom. Prince William and Kate Middleton’s children also all have Cambridge in their name. However, that could change if Prince William becomes the Duke of Cornwall when his father ascends the throne, or once he is king.

Countess of Strathearn

Duchess of Cambridge isn’t Kate Middleton’s royal title in Scotland. Instead, she goes by the Countess of Strathearn, to match Prince William’s Earl of Strathearn title.

Lady Carrickfergus

When visiting Northern Ireland, Kate Middleton’s royal title is Lady Carrickfergus, as Prince William is Baron Carrickfergus.

Is Kate Middleton a princess?

According to her royal title, Kate Middleton is not technically a princess. However, some consider her a princess of Britain by marriage. That said, once Prince Charles is king, Kate Middleton’s royal title could officially change to include princess.

Prince Charles currently holds the Prince of Wales title, which is a special peerage granted to the heir apparent. Once Prince William is heir apparent, his father could make him the new Prince of Wales, which would make Kate Middleton the Princess of Wales.

Prince Charles’ wife, Camilla Parker Bowles is technically Princess of Wales right now. However, since the title is widely associated with Princess Diana, she goes by the Duchess of Cornwall instead.

Future titles

Because Kate Middleton is married to Prince William, who is currently second in line to the throne and is the mother of a future king (Prince George), her royal title will likely change a few times in her life. Here are the royal titles Kate Middleton might receive:

Princess of Wales

As we previously mentioned, Princess of Wales coincides with Prince of Wales — a title given to the heir apparent by a reigning monarch. If Prince Charles appoints this title to Prince William, Kate Middleton automatically receives the Princess of Wales title. However, she can choose to go by duchess instead (like Camilla does).

Duchess of Cornwall

Another title often associated with the heir apparent is Duke of Cornwall, as it can only be used for the monarch’s eldest son. If Prince Charles names Prince William the Duke of Cornwall, Kate Middleton becomes Duchess of Cornwall.

Queen Consort

What will Kate Middleton be called when William is king? According to some reports, she likely will adopt a title similar to her great-grandmother-in-law, Elizabeth Bowes-Lyon, the Queen Consort.

Queen Mother

Should Kate Middleton live to see her son, Prince George, ascend the throne, her official title will change to Queen Mother. The title means she is a queen (or former queen, rather) who is also the mother of the current monarch.
