Seo as a Korean Last Name: Spelling, Romanization and Meaning
Seo (서) is a Korean family name. It may also appear as Suh or in other established personal spellings. “Seo” does not have one universal English-language meaning: the meaning and family history depend on the particular Hanja and lineage associated with a person or clan.
For someone researching a name, the most useful distinction is between pronunciation, Romanized spelling, and the Chinese characters (Hanja) used by a specific family. A Latin spelling alone cannot reveal a person’s ancestry or the exact meaning of the surname.
What does Seo mean as a surname?
Seo is the Roman-letter spelling commonly used for the Hangul surname 서. The Hangul syllable represents the Korean reading; it does not by itself specify which Hanja a family uses. Several characters may have the reading “Seo,” so one should not assign a single literal meaning to every family with this surname.
Why might the surname also be written Suh?
Korean names have been romanized in different ways over time, and families may retain a spelling used in passports or long-standing records. The National Institute of the Korean Language’s research on surname romanization documents variation in how Korean surnames are written in Latin letters. FamilySearch’s Korean surname entry also lists Seo and Suh for 서. For an individual, use the spelling the person or official record uses.
Names and spellings are also entities that businesses need to represent accurately online. If your website needs clearer discovery and messaging, see SEO services and copywriting support.
How to research a particular Seo family
- Ask which Hanja the family uses; do not infer it from “Seo” or “Suh.”
- Check family records or a documented clan genealogy where appropriate.
- Use a person’s own preferred Romanization in names, citations, and correspondence.
- Separate general surname references from claims about one individual’s lineage.
Common misunderstandings
Seo is not a single clan and does not automatically mean one specific character. Different Latin spellings do not necessarily mark different Korean surnames, and similar Roman spellings can have unrelated origins in other languages. Avoid claiming a precise family origin without records that support it.
Frequently asked questions

Yes. Seo (서) is used as a Korean surname.
Are Seo and Suh the same surname?
They can be different Romanized spellings of the Korean surname 서, but an individual’s own recorded spelling should be respected.
Can I tell a Seo family’s Hanja from the Latin spelling?
No. The Latin spelling alone does not identify the characters or lineage. Consult family or reliable genealogical records.
