Young Posse is a girl group that debuted in October 2023 with the EP Macaroni Cheese under the label DSP Media, in collaboration with Beats Entertainment. The group consists of five members: Sunhye, Yeonjung, Jiana, Doeun, and Jieun.

Their debut song Macaroni Cheese was written by Sunhye during a songwriting class after she saw a poster of a macaroni cheeseburger. Their name is derived from the Latin word “posse,” not the English one as some might initially think. “Posse” means “to be able,” so together the band name “Young Posse” means a young group that has come together for a specific purpose.

In early 2024, Young Posse also announced their fandom name, “Teleposse,” which represents the connection between the fans and the band, like telepathy.
