Is Gangnam a City or District? One of Seoul's 25 Gu

Gangnam is not a city. Gangnam District (Gangnam-gu) is one of Seoul's 25 districts. In casual talk, though, people often use “Gangnam” more broadly for Gangnam-gu, Seocho-gu and Songpa-gu together, south of the Han River. That gap is why the name confuses so many first-time visitors. Below is a plain three-layer guide to what people mean when they say it.

Gangnam is one of Seoul's 25 gu, and Seoul is the city

Think of it as three layers. Seoul is the city. Gangnam-gu is the official district inside it. “Gangnam” in everyday speech is a wider region made of three districts. The table below lays out the three layers side by side.

Layer	Name	What it is
City	Seoul	The capital and the city itself
Official district	Gangnam-gu	One of Seoul's 25 districts (gu)
Everyday “Gangnam”	Gangnam-gu, Seocho-gu, Songpa-gu	A wider region south of the Han River

A gu is a district-level unit. Gangnam-gu is classed as an autonomous district within the Seoul capital area, which Koreans call Sudogwon. Addresses show it too, for example Apgujeong-dong, Gangnam-gu.

What Gangnam means in English: literally, “south of the river”

A wide river with a pedestrian bridge, apartment blocks and towers rising on the far southern bank.

Gangnam literally means “south of the river.” The river is the Han, which runs through Seoul. In the broadest sense, the word can point to all of Seoul south of it. The most common use is narrower: the wealthy trio of Gangnam-gu, Seocho-gu and Songpa-gu.

The river matters for history too. Before the 1960s, this side of the Han was little more than farmland. The river was traditionally Seoul's southern edge. Gangnam District came into being in 1975, split off from the southern part of Seongdong-gu. So where is Gangnam today? On the south bank of the Han, in the southeast of Seoul.

Why people call it a city, and the mix-ups to avoid

Is Gangnam in Seoul? Yes. It sits inside the capital, in the southeast. So why does “city” keep coming up? Because Gangnam acts like a city for many Koreans. It is Seoul's commercial center and a well-known trend leader. Casual talk sometimes calls it a city that leads Korea. English-language pages even label Gangnam-gu a “City District,” which blends the two words.

The name also points at more than one thing, so no single label fits every sentence. Someone who says they live in Gangnam may mean Gangnam-gu or the wider region. Answering “district” alone misses that wider meaning. Answering “city” misses that it is part of Seoul. A handy habit: if you are given an address, look for “Gangnam-gu” in it.

Gangnam-gu in numbers: 12 dong and over 550,000 residents

Now the official district on its own. Gangnam-gu is the third-largest of Seoul's districts. It is made up of 12 dong, the neighborhood-level units. More than 550,000 people live there at present.

Item	Fact
Rank among Seoul's districts	Third largest
Neighborhood units	12 dong
Residents	More than 550,000
Gross regional domestic product, 2019	71.85 trillion won

The economic figure is from 2019, and economic numbers age quickly, so read it as a snapshot rather than today's total. It still shows why the area is called an economic and cultural center of modern Seoul.

Koreans widely see Gangnam as the country's wealthiest area

Is Gangnam the richest district in Seoul? Koreans widely regard it as the wealthiest area in the whole country, and people compare it with Beverly Hills in Los Angeles or the Upper East Side in New York. The 2019 output in the table above fits that image, though one figure only goes so far.

What Gangnam is famous for, and the neighborhoods inside it

What is Gangnam District famous for? Shopping, K-pop, fashion and a pace that never really slows down. It is Seoul's commercial center and a known trend leader, and it stays lively around the clock. Many people first meet the name through Psy's hit song, though the glitz in it is only part of the picture.

Old and new sit side by side here. COEX, K-pop and fashion share the area with Bongeunsa Temple and the Seonjeongneung Royal Tomb. Inside the Gangnam area you will find many neighborhoods, including these:

Apgujeong
Sinsa-dong, where Garosu-gil makes a good starting point for shopping
Samseong
Dogok
Cheongdam-dong, where small galleries are a good place to see contemporary art

The verdict: part of Seoul, with a nickname that reaches further

Gangnam is part of Seoul, and Gangnam-gu is one of its 25 districts. In everyday talk, though, “Gangnam” often stretches to cover a wider area. Keep the three layers of city, district and wider region in mind, and the name will make sense wherever you hear it.
