"Swim" (stylized in all caps) is a song by South Korean boy band BTS. It was released on March 20, 2026, as the lead single of the group's sixth Korean-language studio album Arirang. It is produced by Tyler Spry and Leclair, and written by James Essien, Sean Foreman, Tyler Spry, Jamison Baken, Ryan Tedder, RM, Kirsten Allyssa Spencer, Derrick Milano, and Pdogg.

Background and release On January 4, 2026, BigHit Music announced BTS's comeback after a four-year hiatus during which they completed their mandatory military service and released solo work. The title of the album, Arirang, was revealed on January 15, referencing the Korean folk song of the same name. On March 3, BTS revealed the album's track listing and production credits, with the seventh track "Swim" highlighted in black, indicating the song is the lead single from the album. Before the release of the album, Hybe's official YouTube channel released two teasers for the song and its music video.

"Swim" was released as the lead single from Arirang on March 20, 2026. On March 23, BTS released the instrumental version. On March 27, the remix album for "Swim", titled Keep Swimming, was released. The nine-track album includes the original and instrumental versions of "Swim", as well as seven remixes reflecting each member's musical taste. In the United States, "Swim" was also sold by Target as a four-inch "tiny vinyl" with the song "Normal" on the b-side.

Composition and lyrics "Swim" has been described as alternative pop and synth-pop. The song is in common time in the key of C-sharp major with a tempo of 92 to 96 beats per minute. BTS' vocal range span from C♯3 to E4. The lyrics are entirely in English. BTS member RM, who is the main songwriter of "Swim", said: "I wrote the lyrics and I tried to express the confusion that we all had before [and] after the military... and we want to just keep swimming." RM said the track has a "clean and smooth allure", and has compared it to Pyongyang naengmyeon.

In a statement, BTS wrote: "[It's] a song that mirrors life itself. [We] hope it resonates with many people as they move through each day, taking each moment as it comes, splashing along and continuing to swim forward. The more you listen, the warmer it feels, so [we] hope it becomes a source of strength as people go through their lives. Also, just like the folk song 'Arirang,' which has been passed from mouth to mouth and stayed with people through generations, [we] hope 'Swim' will remain close to people's hearts for a long time to come."

The music video surpassed 5 million views within an hour, while trending at #1 in 70 countries.

The music video begins with Lili Reinhart strolling through a display of ship models in a museum while examining her compass.

Copyright lawsuit In July 2026, several songwriters filed a copyright infringement lawsuit in the United States District Court for the Central District of California against Hybe, Hybe America, Big Hit Music, Hybe Music Services, Artist Publishing Group, and several credited songwriters of "Swim". According to the complaint, the plaintiffs alleged that the song copied protected elements from an unpublished demo they had written in 2025. The complaint sought damages and other relief, including an injunction against further exploitation of the song or, alternatively, songwriting credit and a share of the song's profits. RM, although credited as a songwriter on "Swim", was not named as a defendant.

Big Hit Music denied the allegations, stating that "Swim" is an original work and that the complaint contained only the plaintiffs' unilateral claims. The company said it would respond through the legal process. As of July 2026, the lawsuit remained pending and no court had ruled on the allegations.
