Buck-Tick (stylized as BUCK-TICK) is a Japanese rock band formed in Fujioka, Gunma in 1983. The group consisted of lead vocalist Atsushi Sakurai, lead guitarist Hisashi Imai, rhythm guitarist Hidehiko Hoshino, bassist Yutaka Higuchi and drummer Toll Yagami from 1985 until Sakurai's death in 2023. The band has experimented with many different genres of music throughout their four decade career, including punk rock, gothic rock and industrial rock. Buck-Tick are commonly credited as one of the main founders of the visual kei movement.

The band have released twenty-three studio albums and forty-three singles as of 2023, nearly all reaching the top ten and twenty positions on the Japanese Oricon charts. Buck-Tick released both their debut independent and major studio albums in 1987, and achieved breakthrough success the following year with the album Seventh Heaven (#3) and the single "Just One More Kiss". In 1989, Taboo became their first number-one album. It was followed by several successful albums almost all of which topped the charts, Aku no Hana (1990, which includes the song of the same name; the band's only number-one single), Kurutta Taiyou (1991), Darker Than Darkness: Style 93 (1993), Six/Nine (1995), as well as the remixed album Hurry Up Mode (1990 Mix) and the compilation album Koroshi no Shirabe: This Is Not Greatest Hits (1992).

Buck-Tick reached their commercial peak in the mid-1990s (when they were dubbed a "top rock act" by Billboard), but unlike other acts in the visual kei movement, they never ceased activities or faded into obscurity. The band has continued to tour and record regularly in the subsequent decades, and their last five studio albums between Arui wa Anarchy (2014) and Izora (2023) all reached the top six positions on the Oricon and Billboard Japan charts. Making them a rare example in Japanese music history and earning them a special "Inspiration Award Japan" at the 2017 MTV Video Music Awards Japan.
