"Havana" is a song recorded by Cuban-born American singer Camila Cabello featuring guest vocals from rapper Young Thug. It was released on August 3, 2017 as a promotional single of her upcoming debut album The Hurting. The Healing. The Loving., along with "OMG". On August 30, via Twitter, Cabello confirmed the song as the album's second single. It impacted UK radio on September 8. Due to her discarding "Crying in the Club" from the album, "Havana" became its proper lead single.

"Havana" is a mid-tempo track, and lyrically finds the singer embracing her Cuban heritage. Cabello sings the chorus over Latin-influenced piano riffs and rhythm. Sadie Bell of Billboard interpreted the line "Half of my heart is in Havana" as the song chronicling "a romance that found Cabello's heart left down south," while for Rolling Stone's Brittany Spanos, in the "clubby, smooth" track, Cabello falls in love with "a mysterious suitor from East Atlanta," though she has left her heart in her hometown. Young Thug performs a sing-song verse over the "bouncy" piano. Some music publications described the song as "Latin fusion" and pop.

Writing for Billboard, Sadie Bell expressed that the "sexy" track radiates a Latin flare." Similarly, Much's Allison Browsher opined the track "arrives just in time to keep the summer heat going on the radio." Raise Bruner of Time.com wrote that "Havana" "hits a freshly sultry note that we hope to see more of in her September debut album." Peter A. Berry of XXL opined Young Thug's verse "blends with the bouncy piano perfectly."
