Cairo is a first name typically given to boys, but in rare cases also used as a girls name.
The name Cairo isn’t among the current fashionable names in our top 10 stats, but nonetheless, it’s still very popular and common. In our SmartGenius ranking of all boys names, Cairo ranks 505. Recently, out of every 10,000 newborn boys, approximately 3 were named Cairo. If you polled the whole US population – children, adults and seniors – you’d find less than one in 10,000 to be named Cairo.
The name Cairo is derived from the capital of Egypt, which is called al-Qāhirah in Arabic. The name of the city means ‘the victorious’. A predecessor settlement Cairos was founded in the 1st century AD by Romans, today more than 10 million people live there.
Cairo is also a surname... and first appeared as a given name in Brazil in the 1980s.
Cairo is a fairly recent phenomenon. In the past, the name wasn't really on the radar of expectant parents. Then, unexpectedly, Cairo cried out for attention, reaching its peak in popularity at #287 in our SmartGenius statistics in the year 2022. People over 50 probably didn't have classmates named Cairo, for there were many years in which not a single parent chose this first name for their son. Although it also has never been in the top 100 of most popular first names, Cairo seems to have been in vogue for a while, especially since the beginning of the new millennium.
In years where the graph has no value, the name Cairo was given less than five times or even none at all in the entire USA.
You may not know anyone named Cairo, but there’s a good chance you live in the same state as someone with that name. In fact, 37 states are home to men and boys named Cairo. (To be fair, a given name is only included in a state’s official statistics if there are at least five people with that name living in that state – so it’s entirely possible that there are still a few men and boys named Cairo living in one state or another. If your name is Cairo and you live outside of the states highlighted on the map, please let us know so we can refine our statistics even further). And while the first name is present in many states, it is still not one of the popular ones. In Nevada, which has the most people named Cairo relative to the population, you still have to ask 6,816 men and boys their names before you hear Cairo as an answer just once.
Well, you might say, you probably figured that out yourself! But what you might not know is: The letter C is a frequent initial letter for boys’ names. This is because 5.2% of all common boys’ names in the US begin with this letter. The most common first letters of boys' names, by the way, are J, A and D.
With five letters, the name Cairo is comparatively short. In fact, 17.0% of all common first names in the US consist of exactly five letters. Only 7% of all first names are even shorter, while 75% have more than five letters. On average, first names in the US (not counting hyphenated names) are 6.5 letters long. There are no significant differences between boys' and girls' names.
With 5.2% of all boys' names that begin with a C, this first letter is thus much more common than the average of all letters. And which boys’ name beginning with C do you think is the most common in the US? The answer is... Charles.

In these situations, you can communicate your name in so many other ways: you call spell it, sign it, or even use a flag to wave it...
