Red (Taylor's Version) is the second re-recorded album by the American singer-songwriter Taylor Swift. It was released on November 12, 2021, by Republic Records. A re-recording of Swift's fourth studio album, Red (2012), it is part of her re-recording projects following the 2019 dispute over the ownership of her back catalog.

Red (Taylor's Version) includes re-recorded versions of Red and the 2012 charity single "Ronan", as well as nine tracks denoted as "From the Vault": six unreleased songs, a 10-minute-long version of "All Too Well", and solo versions of "Better Man" (2016) and "Babe" (2018), which Swift had written for other artists. Swift and most original producers reprised their works on the re-recorded tracks with additions from Christopher Rowe, and the vault tracks featured inputs from Aaron Dessner, Jack Antonoff, Elvira Anderfjärd, and Espionage, with features from Phoebe Bridgers, Ed Sheeran, and Chris Stapleton.

Music critics described Red (Taylor's Version) as an eclectic album combining styles of pop, country, rock, and electronic, featuring various instruments such as acoustic strings and electronic keyboards. Its songs address the different dynamics of love and heartbreak. Met with unanimous acclaim, the album received critical praise for Swift's vocals, its enhanced production quality, and the vault tracks. Commercially, Red (Taylor's Version) topped the charts in Australia, Canada, and the United Kingdom, among others. In the United States, it was Swift's fourth number-one on the Billboard 200 in less than 16 months, registering the shortest time span for an artist to collect four number-one albums.

Swift promoted the album with televised appearances on NBC talk shows and a self-directed short film accompanying "All Too Well (10 Minute Version)". Red (Taylor's Version) broke the record for the most single-week new entries by an artist with 26 of its tracks charting on the Billboard Hot 100; "All Too Well (10 Minute Version)" became the longest song to ever top the chart. The vault tracks "I Bet You Think About Me" and "Message in a Bottle" were promoted as radio singles. Publications have credited Red (Taylor's Version) with popularizing the "Sad Girl Autumn" popular culture phenomenon. The album won a Billboard Music Award, two American Music Awards, and an NME Award.
