Charlotte, the name of the young Princess of Cambridge, is the latest classic name to join Sophia, Emma, Olivia, and Isabella at the top of the popularity list. It is now among the most popular girl names in many English-speaking and European countries.

Amelia is one of the hottest girls' names, a successor to the megapopular Emma and Emily. Amelia, the Number 2 choice in England, is now also comfortably ensconced in the US Top 10, where it ranked as the third most popular name for girls in 2024.

Henry is well and truly back in style. The classic returned to the Top 10 in the US in 2021 for the first time in over a century, and as of 2024, sits at Number 6. Like James and Theodore, Henry is a strong, traditional name that also manages to feel stylish and gentle.

James is one of the classic Anglo-Saxon names, a stalwart through the ages that is more popular—and yes, stylish—than ever today. It recently came out Number 1 in a poll of America's favorite boys' baby names, and is the most common male name, counting people of all ages, in the US.

William is one of the most enduring of classic names for boys. It's also among the most popular boys' names, as American parents see it as being ideally conservative yet contemporary, and hands-down the most popular baby name beginning with W of all time.

Benjamin is a biblical name that has enjoyed widespread favor for decades, ranking in the US Top 50 for almost half a century and the Top 10 from 2015 until 2023.

Levi, lighter and more energetic than most biblical names, with its up vowel ending, combines Old Testament gravitas with the casual flair associated with Levi Strauss jeans.

Michael was the Number 1 American boys' name for almost half a century. While Michael has moved out of the Top 10 baby boy names, it's still widely used.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.

A solid classic with plenty of history, Thomas strikes the balance between strength and gentleness. A favorite in the UK, a staple in France, and Australia, and never absent from the US Top 100, Thomas feels like a safe bet and a name that fits into any era.

Emily may have dropped somewhat in the current standings, but it was the most popular girls' name for over a decade because it appeals on many levels: Emily is feminine, classic, simple, pretty, and strong. Emily is Number 1 among Gen Z names. It also has those nice literary namesakes, like Emily Dickinson and Emily Brontë.

David is an enduring worldwide classic, used from ancient times to the present day.

Biblical Jacob ceded his Number 1 spot to biblical Noah, in 2013, after holding first place on the list of baby boy names from 1999 to 2012, given a huge boost by the Twilight phenomenon.

Charles derives from the Germanic name Karl, meaning "man" or "free man", and is a royal name in multiple European countries. A famous early bearer is Charlemagne, King of the Franks and Lombards and then Roman Emperor in the 8th-9th centuries.

Adeline has a lovely, old-fashioned "Sweet Adeline" charm, but has become so popular in the US under so many spellings and variations — with Adalynn and Adalyn also popular — that considered together it is far more popular than it first seems. Adorable nickname Addie is also pervasive.

The name August is at its highest point since the 1890s, when it ranked among the Top 100 boy names in the US – and deservedly so. With its great meaning, historic roots, and cool nicknames, 2024 saw August officially re-enter the Top 100.

Jonathan was derived from the Hebrew name Yehonatan, eventually contracted to the modern Yonatan, meaning "gift of Jehovah." It comes from the elements yeho, in reference to God, and natan, meaning "to give." In the Old Testament, Jonathan was the valiant eldest son of King Saul, and it was his friendship with brother-in-law David that gave rise to the expression "Jonathan and David" to describe devoted, steadfast friends.

Sarah was derived from the Hebrew word sarah, meaning "princess." Sarah is an Old Testament name — she was the wife of Abraham and mother of Isaac. According to the Book of Genesis, Sarah was originally called Sarai, but had her name changed by God to the more auspicious Sarah when she was 90 years old.

Caroline is a perennial classic, one of the elite group of girls' names that's ALWAYS ranked among the Top 1000 and that's been in the Top 100 since 1994. Elegant yet strong, Caroline calls to mind the Kennedy Camelot years and Princess Caroline of Monaco.

Adam -- a primal Old Testament name -- was revived as a 1960s cowboy name. Adam is not as popular as it once was and feels ready for a respite, replaced by newer A names like Aidan/Aiden, Avery and Axel. Its most prominent current bearers include Adams Sandler, Levine, Brody and Driver -- who plays a character named Adam on Girls.
