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). Prior to the album's release, Big Machine Records made the song available for digital download on October 5, 2010. Swift was inspired to write "Speak Now" after learning that an ex-boyfriend of her friend would marry someone else. In the lyrics, a protagonist interrupts a wedding in an attempt to win her ex-lover back. Produced by Swift and Nathan Chapman, it is a pop song led by acoustic guitar, and incorporates a 1950s rock chord progression in its refrain.

Music critics lauded the narrative lyrics and production of "Speak Now"; some picked it as an album highlight. The song peaked at number eight on both the Canadian Hot 100 and the US Billboard Hot 100, marking Swift's sixth top-ten debut on the latter and making her the first artist with six US top-ten debuts. It also charted on the Hot Country Songs chart and was certified gold by the Recording Industry Association of America (RIAA) for 500,000 US digital sales. "Speak Now" additionally reached number 20 in Australia and number 34 in New Zealand.

A re-recorded version, 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. The song peaked at number 24 on the Billboard Global 200 and entered on the charts in Australia, Canada, New Zealand, the Philippines, and the US.
