Playful Kiss (Korean: 장난스런 키스; RR: Jangnanseureon Kiseu; (also known as Mischievous Kiss or Naughty Kiss) is a 2010 South Korean romantic-comedy television series, starring Jung So-min and Kim Hyun-joong. It aired on MBC from September 1 to October 21, 2010, on Wednesdays and Thursdays at 21:55 for 16 episodes.

It is based on the Japanese manga Itazura Na Kiss written by Tada Kaoru. The Korean series is the third television adaptation of the manga following the Taiwanese It Started with a Kiss in 2005, and its sequel They Kiss Again in 2007. Though Playful Kiss received low ratings in South Korea in the five to seven percent range, it was sold to 12 countries in Asia for approximately US$3,400,000 and developed a strong cult following, having been streamed 70 million times on Viki and earning US$400,000 in ad revenue through online streaming. Due to its international popularity, a short special edition was aired on YouTube after the series finale.
