Hanabie. (Japanese: 花冷え。Stylized: HANABIE.) is a Japanese nu metalcore band from Tokyo, formed in 2015. The band consists of vocalist Yukina, guitarist Matsuri, bassist Hettsu and drummer Chika. They are known for combining loud and heavy music with contrasting Harajuku aesthetics in a style self-described as "Harajuku-core". Their songs incorporate elements of metalcore, hardcore punk, and nu metal, with a blend of hip hop and electronica.

The band was formed by four high school friends due to their shared admiration of Maximum the Hormone, as a part of their light music club activities. Initially a cover band, they soon transitioned into writing original music, self-producing their first single in 2016. After a period as an independent band, during which they released an album and an EP, they were signed by Epic Records Japan, a subsidiary of Sony Music Japan in 2023. In the same year, their second album Reborn Superstar! was released, ranking 24th on Billboard Japan's weekly album charts. The success of the album led to international recognition and appearances at various music festivals outside Japan.

The band name Hanabie. (花冷え。, "chilly spring weather"), is a reference to the birthdays of the four founding members, all of whom were born during winter or spring. The " 。" signifies progress and was adopted from the name of another band the members were fans of during their middle school years. Their music has featured on DMM TV drama Kenshiro ni Yoroshiku and Japanese variety show Kannai Devil.
