"Jet Coaster Love" (ジェットコースターラブ^?, Jetto Kōsutā Rabu) is the third Japanese single of South Korean girl group Kara. The single was originally set to be released on March 23, 2011, but following the 2011 Great Tohoku Earthquake and tsunami disaster in Japan, the physical single was postponed to April 6, 2011. In order to help out the areas affected by the disaster, the group had decided to donate all proceeds from the sales of this single, both physical and digital, to relief efforts. It eventually became the group's first single to reach #1 on Oricon Daily and Weekly charts.

It was released in three different editions, 1 regular edition and 2 limited editions. The full single (excluding the bonus track) was released on iTunes Japan in March 16, 2011.

It was announced on January 26, 2011, that TBC (also known as 'Tokyo Beauty Center'), the largest aesthetic beauty salon chain in Japan is scheduled to release a commercial featuring all five members of group next month despite the ongoing controversy the group was facing with three of its members desiring to terminate their contracts. The group teamed up with TBC to headline the campaign, “Kirei wa, TBC kara” (“Beauty comes from TBC”). The group's name “Kara”, which also means “from” in Japanese, was cleverly incorporated into the slogan in order to further promote the group’s position as spokespersons. However, it was still undecided as to whether or not the commercial theme song, "Jet Coaster Love", will be distributed digitally in the future.

It was later announced that it would be the group's third Japanese and will be receiving a physical release on March 23, 2011. It will be released in three different editions, 1 regular edition and 2 limited editions. The regular edition will feature a bonus track, “SOS (Army Slick’s 2011 bavtronic mix)". The Limited Edition A will come with a DVD with the promotional video, dance version and behind the scenes footage, and the Limited Edition B will come with a 32-pages photobook.

Following the 2011 Tōhoku earthquake and tsunami in Japan, Universal Sigma made an announcement that it will be postponing a number of its releases to different dates including Jet Coaster Love to April 6, 2011. The group later announced that they will be donating all their income from the single (both digital and physical) in order to help out with the Japanese relief and rescue efforts.
