New Year's Day (Taylor Swift song)

"New Year's Day" is a song by the American singer-songwriter Taylor Swift from her sixth studio album, Reputation (2017). She wrote and produced the song with Jack Antonoff. "New Year's Day" is a sparse acoustic ballad built on recurring piano riffs and subdued guitar and synths. In the lyrics, Swift's narrator spends the morning after a New Year's Eve party with a lover, and they together clean up their shared house and care for each other. Big Machine Records released the song to US country radio as a single on November 27, 2017.

"New Year's Day" received widespread critical acclaim for the intimacy and vulnerability portrayed in its lyrics and simple production. Many critics regarded the song as a standout on Reputation and have considered it one of Swift's best songs. The track charted in the lower-tier ranks on several Billboard charts, including Country Airplay, Hot Country Songs, and Canada Country.

Swift performed "New Year's Day" live on The Tonight Show Starring Jimmy Fallon on November 13, 2017; as part of a medley with her 2010 track "Long Live" on her 2018 Reputation Stadium Tour; and as a "surprise song" four times on her 2023–2024 Eras Tour. "New Year's Day" was interpolated by Olivia Rodrigo in her 2021 song "1 Step Forward, 3 Steps Back".
