Speak Now (song)

"Speak Now" is a song written and recorded by the American singer-songwriter Taylor Swift from her third studio album, Speak Now (2010). Before the album's release, Big Machine Records issued it on the iTunes Store on October 5, 2010. Swift conceived the track after learning that her friend's former lover would marry someone else and produced it with Nathan Chapman. A country rock and pop song, "Speak Now" has lyrics about a protagonist interrupting a wedding in an attempt to win her ex-lover back.

Music critics lauded the narrative lyrics and production of "Speak Now"; some picked it as an album highlight. The song entered on charts of countries worldwide, reaching Australia, New Zealand, and South Korea and peaking within the top ten in Canada and the United States. It also received certifications in Australia and the US. Swift sang "Speak Now" during the concerts of her Speak Now World Tour (2011–2012)—where one of its performances was included on the tour's associated live visual album—and occasionally at certain dates of later tours.

In an effort for Swift to acquire new master recordings of her Big Machine catalog following a 2019 masters dispute, a re-recording of the song, titled "Speak Now (Taylor's Version)", was released as part of her third re-recorded album Speak Now (Taylor's Version) on July 7, 2023. It peaked at number 24 on the Billboard Global 200 chart and reached several countries worldwide, including those in Europe, North America, Oceania, and Southeast Asia. In publication reviews of Speak Now (Taylor's Version), the re-recording generally received praise for retaining the original song's appeal and for Swift's vocals.
