Which two songwriters co-wrote Taylor Swift’s “august”?

Taylor Swift and Jack Antonoff co-wrote Taylor Swift’s “august.”

Antonoff created the instrumental first and sent it to Swift. According to accounts of the song’s creation, Swift wrote the lyrics quickly and intuitively after hearing the musical foundation. Their collaboration continued a partnership that had already produced songs on 1989, Reputation, and Lover.

Swift and Antonoff also produced “august” with Joe Alwyn. That distinction matters: Alwyn is credited as a producer, but he is not listed as a songwriter for the track. In the Folklore credits, Swift and Antonoff receive the songwriting credit.

The song’s writing reflects Folklore’s shift toward fictional storytelling. Rather than presenting a straightforward autobiographical confession, Swift and Antonoff built a story about a short summer romance involving invented characters. This fictional approach helped “august” stand apart from many earlier Swift songs.
