H.O.T，韩国第一代偶像团体。成员有队长文熙俊、Kangta、李在元、张佑赫、Tony An，1996年出道，2001年解散。解散后，安七炫与文熙俊各自发行了个人专辑，而张佑赫，安胜浩和李在元离开了SM Entertainment，与Yejeon Media签约，组成了新团体JTL。「H.O.T」这个名称本身是缩写，全写是「High-five of Teenager」，指的就是五位活力充沛的青少年。所以，念法为一个一个单字念「H.O.T」而非英语的单字「HOT」。

H.O.T打破了当时对于舞曲团体的刻板印象，一个团员负责唱歌，其它人则负责Rap或合音或舞蹈部份，H.O.T与众不同的特色是个个都能舞能唱，成为超越偶像的实力派少年团体。

H.O.T. (Hangul: 에이치오티) was a popular five-member South Korean boy band in the mid to late 1990s. They were formed by SM Entertainment in 1996 and disbanded in 2001. In addition to South Korea, the band was popular in ******, People's ***************** and Korean and Asian communities in the Americas. H.O.T. was the first group to have an album become a "million seller" in K-pop, despite there being a financial crisis in South Korea at the time.
