10-second answer
What does Sunbae (선배) mean?
선배 (sunbae) means someone who entered your school, company, or field before you — a senior. The opposite is 후배 (hoobae), someone who came after you. It's about join order and experience, not just age.

선배 vs 후배
| Word | Meaning | Address directly? |
|---|---|---|
| 선배 (sunbae) | Entered before you — your senior | Yes: 선배! or politely 선배님 |
| 후배 (hoobae) | Entered after you — your junior | No — call them by name |
In real life you'll also hear the name in front: 지민 선배, 지민 선배님. That's the safe way to start. Once people get close at university, a woman may switch to 오빠 for a male 선배 (and a man to 누나 for a female one), usually after being invited to — but in front of professors or in a meeting it goes straight back to OO 선배(님). The 언니 vs 누나 page covers the same kind of switch.
Notice the asymmetry — the same one you saw with 동생: you address upward with a title (선배), but downward with a name. Hierarchy in Korean shows up exactly in these details.
선배 or 선배님?
Adding 님 raises the respect level. As a rule of thumb: 선배님 at work or with a large gap in seniority, 선배 at school between students who are reasonably close. K-dramas set in high schools and universities are full of both.
선배님, 먼저 가 보겠습니다.
seonbaenim, meonjeo ga bogetseumnida.
Sunbaenim, I'll head out first.

It's Not (Only) About Age
A 선배 can be younger than you. If a 25-year-old joined the company two years before a 30-year-old newcomer, the 25-year-old is the 선배 at work. Join order beats birth year inside institutions — though in practice, age still shapes how politely people speak to each other.
This is why 선배/후배 doesn't map onto 형/누나/오빠/언니: those are age words, while 선배/후배 are experience-order words. The two systems run in parallel.
Common Mistakes
Mistake #1 — "Sunbae = older person"
선배 marks who came first, not who was born first. An older newcomer politely calls a younger senior 선배님 in many workplaces.
Mistake #2 — Addressing a 후배 as "후배!"
Like 동생, 후배 describes the relationship. Face to face you use their name.
