DIA (Hangul: 다이아), shortened from DIAMOND and standing for Do It Amazing, is a six-member South Korean girl group. It is formerly under MBK Entertainment and PocketDol Studio. The group consists of Eunice, Jueun, Huihyeon, Yebin, Chaeyeon and Eunchae. Former members include Seunghee, Eunjin, Jenny and Somyi.

The group debuts with the album Do It Amazing. It later releases its second album, YOLO, and its sixth and final EP, Flower 4 Seasons. In May 2020, the group transfers from MBK Entertainment to PocketDol Studio ahead of a comeback. In September 2022, its contracts with PocketDol Studio expire and all members leave the company. The group then goes on hiatus, with the members focusing on individual activities, while Yebin says the group does not disband and may still promote and release music together in the future, though under different agencies.
