"Lover" is a song by American singer-songwriter Taylor Swift for her seventh studio album of the same name (2019). Swift wrote the song and co-produced it with Jack Antonoff. Republic Records in partnership with Taylor Swift Productions released it as the third single from the album on August 16, 2019. Musically, "Lover" is a country ballad that features a booming snare, slow tempo and guitar-centric sound. Over a retro-styled musical motif, Swift sings lyrics about devotion on the song; which several publications interpreted to be about her partner Joe Alwyn.
"Lover" received acclaim from critics, who praised its nostalgic quality and Swift's songwriting. In the US, the song peaked at number 10 on the Billboard Hot 100, becoming the album's third consecutive Hot 100 top-10 single. It also entered the top 10 on charts in Australia, Canada, Ireland, Malaysia, New Zealand and Singapore.
Swift and Drew Kirsch directed the "Lover" music video featuring dancer Christian Owens as her love interest. Premiering on August 22, 2019, the video features bright colors and a dollhouse setup, showing the couple fighting and making up. Swift performed the song at the 2019 MTV Video Music Awards.
