This article discusses the Top 40 Best and Highest Rated Korean Dramas of All Time and does not contain any major plot points or spoilers.

Over the last half a decade or so, Korean Dramas (or K-Drama) have really picked up steam in terms of their global popularity. In part, this is thanks to Netflix’s consistent investment in the country’s content, whether through their own original projects or the licensing of existing offerings that then brings them to a much broader audience. However, with so much out there, to the uninitiated, it can be hard to find the perfect jumping-in point. Do you go with the most popular? What seems the most buzz-worthy online? A mix of the two?

Here, at Ready Steady Cut, we thought it’d be handy to present the Top 40 Best and Highest Rated Korean Dramas of all time according to their Nielsen rating on cable TV in Korea. This rating is illustrated by a percentage, which shows the share of audience that a show had at a given time. So, if something has a Nielsen rating of 4%, that means that 4% of the public with a television were watching the Korean Drama at the time.

So, if you’re looking for a comprehensive list of shows that were amongst the most popular with the domestic Korean audience, or if you’re just in need of something new to watch, look no further than here with our Best and Highest Rated Korean Dramas of all Time.
