2,401 Korean actors, singers and other entertainers are in their 40s as of 2026 — that is, born between 1977 and 1986. 1,782 of them are named on this page. They are 26.0% of the 9,225 people we hold.
Ages move; birth years do not. Everyone here was born between 1977 and 1986, and that will still be true whenever you read this. The words “in their 40s” are true as of 2026, the year this page was built — so if you are reading it later, count from the birth years rather than from us.
Ordered by how many Wikipedia language editions carry an article about them. That measures how widely someone is written about, not how good they are, and it favours people who have been famous longer.

A dash means we hold no figure, not a zero.
This page groups by age. If you know the date, the birthday pages are the faster way in — one page per month, and one per calendar day.
619 of the 2,401 people in this band are counted but not named. Their only name on Wikidata is written in Korean, and this is an English-language site — a name our readers cannot read would help nobody. We would rather count someone and not name them than leave them out of the count.
A bigger band does not mean more people of that age exist. Who has a Wikidata entry is decided by editors, not by us. More recent performers may simply be written down more often. We hold no way to separate those two, so we do not claim to.
24 people in our roster are younger than the youngest band here. Their birth years are known — we do not publish an age page about children.
