You’re at a crowded airport. Maybe it’s Heathrow, or perhaps Istanbul’s massive hub. You shout the name "Muhammad" across the terminal. Honestly? At least a dozen people are going to turn around. This isn't just a hunch; it’s a statistical reality of our modern world.
While Westerners often guess names like John, James, or even the trending Oliver, they’re usually thinking within a very small, English-speaking bubble. If we’re looking at the big picture—the whole planet—the numbers tell a much different story.
The most common first name in the world is Muhammad.

When you factor in all the various regional spellings like Mohammed, Mohammad, Mehmet, and Mamadou, experts estimate that over 150 million people carry this name. To put that in perspective, that’s more than the entire population of the United Kingdom and Germany combined, all sharing one moniker.
Why the World is Full of Muhammads
It’s not just a trend. It’s a deep-rooted cultural and religious practice that has remained steady for over 1,400 years. In many Muslim families, there is a tradition—sometimes even seen as a spiritual obligation—to name the first-born son after the Prophet of Islam.
It’s a way to seek a blessing. Parents hope that by giving their child this name, they’ll inherit the noble characteristics associated with the figure. Because of this, the name doesn't really "go out of style" like Western names do.
In the U.S. or the UK, names like Gary or Susan can peak in one decade and basically vanish the next. Muhammad doesn't work like that. It’s a constant.
Even in 2026, the data from the UK’s Office for National Statistics (ONS) shows Muhammad holding the top spot for baby boys in England and Wales. It’s been sitting there, or very near the top, for years.
The Variety of Spellings
One reason people get confused about this is the spelling. Since the name comes from the Arabic script (مُحَمَّد), the way it’s written in the Roman alphabet changes depending on where you are.
- Muhammad: Very common in Pakistan, India, and the UK.
- Mohammed/Mohammad: The standard in many Arab nations.
- Mehmet: The Turkish variation.
- Mamadou: Widely used in West Africa.
When researchers aggregate these, the total population of "Mo’s" becomes staggering. It’s the ultimate global name.

For a long time, Maria has been cited as the most common female first name globally. When you look at the sheer influence of the Spanish and Portuguese-speaking worlds, plus the Catholic traditions in Europe and the Philippines, Maria is everywhere.
However, unlike Muhammad, Maria has some serious competition these days.
Names like Sophia (and its variations like Sofia or Sofija) have been dominating birth registries in dozens of countries simultaneously. In 2025 and 2026, Sophia has consistently ranked as a top-three name in places as diverse as Italy, Russia, and the United States.
Then you have Olivia.
If you look at the most recent baby name data, Olivia is the reigning champ of the English-speaking world. It has been the #1 girl name in the U.S. and the UK for several years running. But on a global, all-time population scale? Maria still likely holds the crown due to the hundreds of millions of older Marias living today.
The Misconceptions About "John" and "James"
You’ve probably seen those old lists that say John is the most common name.
That’s kinda true if you only look at the last 100 years of data in the United States. The Social Security Administration (SSA) will tell you that James and John are the most frequent names on their records. But the U.S. is just one country.
When you cross the border into Mexico, you hit a wall of Josés. In China, names like Wei or Li are shared by tens of millions.
We tend to have a "Western bias" when we think about popularity. We see what’s in our local school registries and assume the rest of the world follows suit. In reality, the most common first name in the world is almost always driven by large, fast-growing populations with stable naming traditions—like those in South Asia, the Middle East, and Latin America.
Surprising Global Contenders
There are a few "dark horse" names that most people never think about, but the sheer size of the populations using them makes them massive.
- Nushi: Often cited in various datasets as a top name in India.
- Jose: Still the powerhouse of the Hispanic world, though often used in compound names like Jose Manuel or Jose Luis.
- Wei: A dominant name in China, often appearing in the top ranks for males.
How to Check the "Real" Popularity
If you’re looking to see what’s actually happening in the world of names right now, don't just look at "all-time" lists. Look at birth trends from the last year.
For 2026, we’re seeing a massive shift toward "nature" names and "vintage" names. Names like Aurelia, Luna, and Noah are skyrocketing globally. Noah, in particular, has become a truly international name, topping charts in Germany, the Netherlands, and the U.S. all at once.
It’s one of the few names that seems to bridge the gap between religious tradition and modern "cool" factor.

Actionable Insights for Naming
If you’re actually trying to choose a name and want to either join the crowd or avoid it, here is what you need to do:
- Check the "Combined" Lists: If you live in a diverse city, look for statistics that combine spellings. A name might look like it’s at #10, but when you add the three different ways people spell it, it might actually be #1.
- Look at Regional Data: In the US, a name might be #1 nationwide but virtually unheard of in your specific state. Regional trends matter more for your daily life than global ones.
- Consider the "Grandparent" Effect: Many names are "common" because older generations have them, not because they are being given to babies today. If you want a name that feels fresh, look at the "fastest-rising" lists rather than the "most popular" lists.
- Think About Portability: If you want a name that works everywhere, look at names like Sofia or Noah. These are recognized and easy to pronounce in dozens of languages, which is why they are currently conquering the global charts.
The world is getting smaller, and our names are reflecting that. While Muhammad remains the most common first name in the world by a long shot, the "Top 10" list for newborns is becoming increasingly similar across every continent.
