3RACHA is the one of the main units of K-Pop group Stray Kids. It consists of leader Bang Chan and rappers Changbin & Han. The name is inspired by sririacha sauce because of the similar pronunciation in Korean; Stray Kids' other main units, DANCERACHA and VOCALRACHA also interpolate 3RACHA’s name.

3RACHA is unit that specializes in production and rap. The three members have writing and production credits on the majority of Stray Kids songs and all have rap positions. They rapped a lot more before they debuted with Stray Kids, releasing mixtapes on SoundCloud under rap stage names: Bang Chan went by CB97, Changbin went by SPEARB and HAN went by J.One. The three still use these names on occasion.

In 2022, the unit was featured on SKY-HI’s “JUST BREATHE,” marking 3RACHA’s first official release.
