BTS had released five Korean-language studio albums as of 2023.
Those albums are Dark & Wild (2014), Wings (2016), Love Yourself: Tear (2018), Map of the Soul: 7 (2020), and Be (2020). The count excludes extended plays such as O!RUL8,2? and Skool Luv Affair, as well as compilations such as Proof.
The number can be confusing because BTS’s discography also includes Japanese-language studio albums, including Wake Up, Youth, Face Yourself, Map of the Soul: 7 – The Journey, and other Japanese releases. Counting every studio album rather than only Korean-language releases produces a larger total.
BTS’s album formats also blur the categories: reissues, repackages, single albums, soundtracks, and compilation albums are listed separately from standard studio albums. That is why a question specifying both “Korean-language” and “studio albums” has the more precise answer of five.
