aespa (stylized as æspa) is a four-member South Korean girl group formed by SM Entertainment in 2020. The group consists of four members: Karina (카리나), Giselle (지젤), Winter (윈터) and Ningning (닝닝). They debuted on November 17, 2020 with the single "Black Mamba".

The group's name, Aespa, combines the English initials of "avatar" and "experience" (Avatar X Experience) with the English word "aspect", meaning "two sides", to symbolize the idea of "meeting another self and experiencing the new world". Each member has a digital version of themselves, referred to as avatars.
