Squid Game (Korean: 오징어 게임; RR: Ojing-eo Geim) is a South Korean survival drama television series created by Hwang Dong-hyuk for Netflix. The series revolves around a contest in which 456 players, drawn from different walks of life but each deeply in debt, play a series of children's games for the chance to win a ₩45.6 billion[a] prize, with a deadly penalty if they lose. The name of the series draws from a similarly named Korean children's game. Its cast includes Lee Jung-jae, Park Hae-soo, Wi Ha-joon, Jung Ho-yeon, O Yeong-su, Heo Sung-tae, Anupam Tripathi, and Kim Joo-ryoung.

Hwang had conceived of the idea based on his own economic struggles early in life as well as the class disparity in South Korea. Though he had initially written it in 2009, he was unable to find a production company to fund the idea until Netflix took an interest around 2019 as part of their drive to expand their foreign programming offerings. All nine episodes were written and directed by Hwang.

Squid Game was released worldwide on September 17, 2021, to critical acclaim and international attention. Attracting more than 142 million member households during its first four weeks from launch, it is Netflix's most-watched series to date.
