"First Love" is a song recorded by American entertainer Jennifer Lopez for her eighth studio album, A.K.A. (2014). It was written by Max Martin, Savan Kotecha and Ilya Salmanzadeh, and produced by Martin and Ilya, with vocal production being handled by Martin, Peter Carlsson, and Ilya. It was released by Capitol Records as the album's second single on May 1, 2014. The song was first developed when Lopez was talking to Martin, Kotecha and Cory Rooney about relationships during a break from the album recording. A day later, they appeared with the lyrics of the track, and Lopez recorded it.

"First Love" is a pop, electropop and R&B song with synth beats, "hard-hitting percussion" and "big drums" as the song's instrumentation, with critics also noting influences from her previous material. Lyrically, "First Love" talks about finding true love and wishing you would have met the person you're with now years ago, so they can be your first love. The song received positive reviews from most music critics, who commended the track for lifting the bar for high-quality pop music, while also praising its "fun and free feel".

Commercially, "First Love" received minor success on the US Billboard Hot 100 chart, but managed to receive moderate airplay on the US Pop Songs and topped the US Hot Dance Club Songs. It also reached the top-twenty in Spain and the top-fifty in Italy. The accompanying music video for "First Love" was released on May 29, 2014 and was directed by Anthony Mandler. The black-and-white music video features British model David Gandy and Lopez during love scenes in a desert. Lopez promoted the track with live performances on the 2014 Billboard Music Awards, American Idol, Late Show with Jimmy Fallon, as well as on her concerts throughout 2014 - blending the song with elements of "Ain't No Mountain High Enough" as well as a dance-break.
