Eo 어 — Korean last name
Is Eo a Korean last name?
Yes. Eo (Hangul: 어, Hanja: 魚) is a Korean family name recorded in the 2015 South Korean census with 18,929 holders, making it the #81 most common of the 191 surnames counted. Roughly one in every 2,626 South Koreans is a Eo. It is uncommon enough that many Koreans will know only a few people who carry it.
How to write Eo in Korean
In Hangul, Eo is written 어. The same Hangul syllable is used by 2 different Hanja (Chinese characters): 魚, 漁. Each character is technically a separate surname with its own clans and ancestry, even though they sound identical and are romanized the same way. The most common by far is 魚.
What does Eo mean?
The character 魚 means fish. As with most Korean surnames, the meaning comes from the Chinese character rather than from the Korean sound, so it says something about how the name was first written down (often a place, a virtue, an object or a Chinese dynasty) rather than describing the family. Koreans rarely think about the literal meaning of a surname in daily life, but it matters for genealogy and for choosing given names that pair well with it.

Eo is uncommon Korean surname. Just above it in the rankings is Kook (20,768) and just below it is Kyung (16,958). For comparison, Kim, the most common surname, has 10,689,967 holders.

Spellings and romanization
Eo is the spelling most Korean families use on passports and in English. The official Revised Romanization (used by the South Korean government since 2000) is Eo, and the older McCune–Reischauer system gives Ŏ. Other spellings you will see in real life include Uh, Eoh, Auh, Eu, Au. The variety exists because Korean passport rules let each family choose its own romanization, so spellings drifted over generations of emigration; in Korean, every one of these is the same 어.
How to pronounce Eo
Eo (어) is pronounced roughly as the Revised Romanization "Eo" reads, with even stress on each syllable — Korean does not stress one syllable over another the way English does. Vowels are pure and short: "eo" is the "u" in "sun", "eu" is a tight "oo" with unrounded lips, and "ae" rhymes with "day".
