FIFTY FIFTY (피프티 피프티) is a South Korean girl group under ATTRAKT, consisting of 4 members, Aran, Keena, Saena, and Sio. They debuted on November 18, 2022, with the mini album The Fifty. The EP became a sleeper hit after gaining critical acclaim and was praised for its sound.

The group returned in February of 2023 with the single album The Beginning: Cupid. Both versions of the title track, “Cupid” became viral hits and earned the group their first Billboard Hot 100 hit. FIFTY FIFTY became the fifth Korean girl group to enter the chart and the fastest Korean group to do so.

In the end of June 2023, the group filed a lawsuit against their agency, ATTRAKT, because the company violated contract terms–specifically an unclear payment settlement. All four members filed an application to terminate their contract with the company.
