"Kuchibiru ni Be My Baby" (唇にBe My Baby)^?, (On-the-Lips Be My Baby) is the 42nd single by the Japanese idol girl group AKB48. It was released in Japan on December 9, 2015. As of February 22, 2016 (issue date), it has sold 1,041,763 copies. It was number-one on the weekly Oricon Singles Chart and was also number-one on the Billboard Japan Hot 100.

The title track of this single marks Minami Takahashi's first time to hold an unshared choreography center position since 2006's "Sakura no Hanabiratachi". The B-side track "365nichi no Kamihikouki" was nominated for the category "Best Song" in the 58th Japan Record Awards but lost.

The single will be released in nine versions: Type A (two editions: limited and regular), Type B (limited and regular), Type C (limited and regular), Type D (limited and regular), and a version called a "Theater Edition". All versions, except the Theater Edition, include a DVD with four music videos (there's a music video for every song included in the particular version) and a video related to Minami Takahashi.

For the first time since "Chance no Junban", AKB48 did not sell a million copies of a single within the first week after the release, breaking the so-called Million Streak that had started since "Everyday, Kachuusha". Kuchibiru ni Be My Baby still managed to sell a million copies after several weeks. "Kuchibiru ni Be My Baby" sold 905.490 copies in 2015, making it the 4th best selling single of the year, according to the Oricon.
