In Korean entertainment, a stage name isn't just a catchy nickname. It's often a carefully curated part of an artist's identity. For many stars, especially K-pop idols, the name they debut with becomes more recognizable than the one they were born with. Take IU or YoonA, for example. Both started in idol groups but are now just as famous for their acting careers, and both are better known by their stage names than their real ones.

While it's common in the idol world, the use of professional names extends to non-idol actresses, too. Some choose new names to avoid confusion with others in the industry, while others pick ones that better reflect their image or are easier for fans to remember. In many cases, fans go years without realizing that their favorite stars are using a stage name at all.

That alone shows just how powerful and lasting a well-chosen name can be in shaping a celebrity's public persona.

Curious who’s been going by a professional name all this time? Here are some of the most popular South Korean actresses whose real names you may not know.
