Korean Name Generator

What the Korean name generator does

So you want a Korean name. For a character, a fan account, a game, a story you are building.

This gives you Korean names in the Latin alphabet. Pull one, or pull a batch and read down.

Then stay, because the thing that is most obviously strange about Korean names has an explanation, and the explanation turns out to be a story about a class system falling apart.

How to use it

Set how many you want, from one to a hundred, and press Generate. Copy takes the set with you.

Four surnames, half a country

You have already noticed it. Read the list for ten seconds and it is Kim, Kim, Park, Lee, Kim, Park.

That is not the list being lazy. That is South Korea.

At the 2015 census, one person in five was a Kim. Twenty one and a half percent, which is a little over ten and a half million people. Then Lee at nearly fifteen percent. Then Park at eight. Then Choi at nearly five.

Four names. About half the country.

There is a saying in Seoul that if you throw a stone off the top of Namsan, the hill in the middle of the city, it will hit a Kim or a Lee. It is not much of a joke. It is close to a statistical claim.

Now, the interesting part is not the number. It is the age of the number.

Because this is recent. This is not a thousand year old distribution that slowly settled. Most of that concentration happened inside the last century and a half, and it happened for a reason that has nothing to do with families having lots of children.

A surname used to be a rank

For most of the Joseon dynasty, which ran for five hundred years and only ended in 1910, a surname was not something you had. It was something you were.

Family names belonged to the yangban. The aristocracy. If you were a commoner, you generally did not have one. If you were enslaved, you certainly did not.

So a Korean surname was not an identifier. It was a badge. It said, out loud, before you opened your mouth, which half of the world you were from.

Then the badge started leaking.

The numbers on this are extraordinary. Census records from one prefecture, reported by Moon Ki-hoon in The Korea Herald, show households with no surname falling from forty five percent in 1681 to six percent by 1816. Nobody passed a law. Over about a century and a half, quietly, household by household, people simply started having surnames. They bought them, they claimed them, they attached themselves to clans that would have them. And what they were buying was not a name. It was the appearance of not being a commoner.

The class system itself was formally abolished by the Gabo Reform of 1894. After that everyone could have a surname, and everyone did.

And when you are choosing a name whose entire purpose is to make you look like you were always somebody, you do not choose an unusual one. You choose the good one. You choose Kim, which had ruled Silla. Or Lee, which had ruled Joseon. Or Park, which had founded Silla.

Which is exactly what happened, at scale, across a whole population, in about a generation.

Now here is the part that gets me, and it is the whole reason this page exists.

Yumi Moon, a historian of East Asia at Stanford, put it plainly: changing a surname you inherited from your ancestors is disgraceful, by the custom of the old world.

Read that against everything above. A name that was picked, deliberately, one afternoon, by somebody trying to get on in life, was inherited by their children. And to those children it was not a choice anybody had made. It was ancestral. It was the thing you do not touch.

One generation's social climb is the next generation's sacred inheritance. It only takes one handover. The receipt disappears and the heirloom remains, and nobody ever finds out which one they are holding.

The part of a Korean name nobody says out loud

So now there is a practical problem. Everybody is a Kim. How does anybody know who is actually related to whom?

Korea already had an answer, and it is one of the more elegant things in any naming system anywhere.

It is called the bon-gwan, the ancestral seat. It is a place, and it sits invisibly in front of the surname.

You are not a Kim. You are a Gimhae Kim, or a Gyeongju Kim, or an Andong Kim. Those are entirely separate clans, each traced to a different founding region, each with its own genealogy going back to its own ancestor. The Kim surname alone carries somewhere around three hundred of them. The Gimhae Kim clan by itself has millions of members. The Gyeongju Kim have millions more.

Two Kims from different seats are not distant cousins. They are not related at all. They share a syllable and nothing else.

And the bon-gwan is not on your name tag. It is not part of how you introduce yourself. It sits on official documents and in the family genealogy, and mostly it lives in the back of people's heads as a thing you would know about yourself.

So every Korean name has a hidden first component. A place, from centuries ago, that does not appear when the name is written or spoken, but which is the only thing that makes the surname mean anything.

The visible name says almost nothing. The invisible part is doing the work.

The law that would not let them marry

And then the bon-gwan got teeth.

Late in the Joseon period, with surnames spreading and nobody entirely sure who was blood and who had simply picked a good name, the king made it a rule: two people with the same surname and the same bon-gwan could not marry.

The reasoning was not unreasonable. If half the country is called Kim, and the clan records are the only thing standing between you and accidentally marrying a cousin, then treat the clan records as the boundary.

But look at what that rule does once it hardens. A Gimhae Kim has millions of clan members. A common ancestor thirty generations back is not a relative in any sense that matters biologically. And yet the law said no.

Two people could meet, have nothing in common but a syllable and a village name from the fourteenth century, and be legally unable to marry each other.

That law survived until 1997.

Not 1897. Nineteen ninety seven. There are people who are still married today who had to wait for it.

So the shape of the whole thing is this. Surnames were a badge of rank. The rank collapsed and everybody grabbed the same few badges. That made the badges useless, so the clan seat became the real name. And the clan seat then decided who was allowed to fall in love, for a century, on the basis of a place that most of them had never been to.

Taking a Korean name apart

Take Min-Joon Kim off the list.

Kim is the surname. Min-Joon is the given name, and it is one name, not two, despite the hyphen.

That hyphen is doing something specific and it trips up nearly every English speaker. A Korean given name is usually two syllables, and each syllable is its own unit of meaning. Min. Joon. Two pieces, one name. It is not a first name and a middle name. It is not Mary and Anne. It is one word that arrives in two parts, and the hyphen is a courtesy to English readers so they can see the joint.

Underneath, most of those syllables come from hanja, the Chinese characters that Korean used for most of its history and still uses for names. Min can mean quick, or clever. Joon can mean talented. Ji, which opens a huge share of the names on this page, tends toward wisdom. Hyun leans to worthy or virtuous. Seo, Soo, Hye, Eun, all of them are carrying a character behind them.

Which means a Korean given name works the same way a Chinese one does. The surname is inherited and effectively fixed. The given name is composed, fresh, out of chosen meanings.

And that is why the two halves of a Korean name behave so differently. The surname pool has collapsed to almost nothing. The given name pool is wide open, because every set of parents is building one rather than picking one.

One half of the name went through history. The other half went through a decision.

How this list was built

Nothing clever, and that is deliberate.

The list underneath was assembled by hand, our team going through each name on its own. Surnames that are genuinely common in Korea, given names that Koreans actually use. Generate pulls names at random, none of them twice in one batch.

This runs in your browser alone, and nothing you type is sent out.

Where it usually goes wrong

The surname goes first in Korea. Kim Min-joon, not Min-joon Kim. English writing flips it, and plenty of Koreans abroad flip it themselves, so both are in circulation. But inside Korea, in Korean, there is one order, and it is family first.

Min-Joon is not two names. Do not put one of those syllables in a middle name field. Do not shorten it to Min. The two syllables are one name and splitting them makes about as much sense as calling somebody Ali because their name is Alison.

The romanisation is a mess and that is not your fault. The same Korean name comes out as Lee, Yi, Rhee or Ri. Park is also Pak or Bak. Kim is stable, everything else drifts, and there is no single right answer because Korea has changed its official romanisation more than once and people simply kept spelling their own names the way they always had. If your character has a passport, they picked a spelling once and stuck with it.

Given names date, hard. Ji-woo, Seo-yun and Ha-eun read as small children. Young-hee and Sun-ja read as somebody's grandmother. If you are writing 1988 and you use a 2018 name, a Korean reader clocks it on the first page.

And if this is for a real person. A name in the Latin alphabet is a sound. The name is the hangul, and behind that usually the hanja. Get somebody who reads Korean to look at the characters before it goes anywhere permanent.

Questions people ask

Why is everyone called Kim?

Because a surname used to mean you were aristocracy, and when the class system was abolished in 1894, the people who had never been allowed one chose the best ones on the shelf. Kim, Lee and Park were the names of ruling houses. Everybody reached for the same three.

Are all the Kims related?

No, and mostly not even slightly. They are divided into hundreds of clans by bon-gwan, the ancestral seat. A Gimhae Kim and a Gyeongju Kim have no more connection than any two strangers.

What is the hyphen for?

It shows the seam between the two syllables of a given name. It is a reading aid for people who do not read Korean. The name is one name, not two.

Which are men's names and which are women's?

Some syllables lean, and a Korean speaker would hear it instantly. Quite a lot of that signal lives in the hanja rather than the sound, so it does not survive the trip into the Latin alphabet. Treat it as missing rather than as neutral.

Do Korean women take their husband's surname?

No. A Korean woman keeps her own surname for life. The children take the father's, so a Korean family routinely has a mother with a different surname from her own children, and nobody finds this remarkable except foreigners.

Can I pick a Korean name for myself?

People do, all the time. The sensible route is the same as anywhere: get a Korean speaker involved before you commit, because choosing characters out of a language you do not read is exactly how people end up with a name that is technically fine and quietly ridiculous.
