Mastermind (song)

"Mastermind" is a song by the American singer-songwriter Taylor Swift, taken from her tenth original studio album, Midnights (2022). She was inspired to write it after watching the 2017 film Phantom Thread. Produced with co-writer Jack Antonoff, "Mastermind" is an electropop song featuring synth arpeggiators, layered vocal harmonies, and an expansive bass. Its lyrics are about a narrator confessing to a lover that they were the one who initiated and planned their romantic relationship.

Music critics generally praised "Mastermind" for its production and Swift's songwriting, with some commenting that the lyrics were not meant to be taken too seriously. The track peaked at number 13 on the Billboard Global 200 and the top 20 on national charts in Australia, Canada, Malaysia, the Philippines, Singapore, and the United States. It received certifications in Australia, Canada, and the United Kingdom. The song was included on the set list of Swift's Eras Tour (2023–2024).
