About Louis
Kate and William shocked the world when they announced that they'd named their third child Louis, or Prince Louis Arthur Charles, to be more precise. But we've been predicting a comeback for this classic name for a long time.
Derived from the Germanic Ludwig, Louis is hugely popular in France, Belgium, and Quebec where it ranks in the Top 10, though it is also on trend in the UK, The Netherlands, Switzerland, New Zealand, Australia, and Germany, where it features in the Top 100.
In the US, Louis was hugely popular in the late 19th and early 20th century and has remained consistently, if more quietly used ever since. It currently features in the Top 300 and has been used by several other celeb parents such as Sandra Bullock and Bill Pullman.
A name with plenty of history, it has long been borne by French royalty, while other bearers include musicians Louis Armstrong and Louis Tomlinson, writer Robert Louis Stevenson, journalist Louis Theroux, and businessman Louis Vuitton.
One thing to keep in mind with this classic is that its pronunciation varies depending on language and preference. In French, LWEE is heard, while in the UK, it is typically said as LOO-ee, though LOO-is may also be heard. In Dutch, it is loo-EE, while in the US, it is mostly LOO-is.
To get around the pronunciation confusion, many parents especially go with Louie, which ranks above Louis in the UK. There's also Lewis, the Medieval English form, and hugely popular in Scotland,
Louis is also given to girls, where it ranks #14230 in the US.
Pronounced LOO-ee.
As of October 2026, Louis ranked #249 in US births in 2025 SSA, peaked at #18 in 1882, Nameberry popularity #76.
