What was BTS's first Korean-language studio album?

BTS's first Korean-language studio album was Dark & Wild.

Released on August 20, 2014, Dark & Wild was the group's first full-length Korean studio album, following the single album 2 Cool 4 Skool and the extended plays O!RUL8,2? and Skool Luv Affair. Its lead single was "Danger," a forceful track about romantic frustration and emotional imbalance.

The album helped establish BTS's early musical identity: hip-hop remained central, but the production also incorporated rock guitar, R&B textures, and electronic elements. Its lyrics continued the group's coming-of-age themes, focusing on youthful desire, impatience, and complicated romance.

A common mix-up is confusing Dark & Wild with Wings, which was BTS's second Korean studio album, released in 2016. Another distinction is that Wake Up, released later in 2014, was BTS's first Japanese-language studio album. Dark & Wild therefore marks the group's first Korean full-length album, not their first album release overall.
