Evermore is the ninth studio album by the American singer-songwriter Taylor Swift. It was a surprise album released on December 11, 2020, via Republic Records, less than five months after her previous studio album Folklore. Evermore was a spontaneous product of Swift's extended collaboration with her Folklore collaborator Aaron Dessner, mainly recorded at his Long Pond Studio in the Hudson Valley.

Swift described Evermore as an offshoot of "the folklorian woods"—an escapist, cottagecore-inspired direction she first ideated with Folklore during the COVID-19 pandemic; she regards them as sister albums. Evermore blends alternative rock, indie folk and chamber pop styles, carried by fingerpicked guitars, somber pianos, lavish strings, and sparse percussion. Impressionist storytelling and mythopoeia dominate its lyrical technique. The subject matter has been described as an anthology of tales about love, marriage, infidelity, and grief, exploring the complexities of human emotion. American bands Bon Iver, Haim, and the National appear as guest performers on the album.

Earning widespread acclaim from critics, Evermore was praised for its character studies, experimental production, and Swift's nuanced vocals. Reviews regarded the album a sequel or a counterpart to Folklore, and various publications listed it in their 2020 year-end rankings. Evermore was nominated for Album of the Year at the 64th Annual Grammy Awards, a second consecutive nomination for Swift in the category after winning it with Folklore the previous year. Dessner and Long Pond have achieved mainstream notability since Evermore's release.

The album reached number one in Argentina, Australia, Belgium, Canada, Croatia, Greece, New Zealand, Portugal, the United Kingdom, and the United States. Republic Records reported over a million copies of Evermore sold in its first week globally. It was Swift's eighth consecutive Billboard 200 number-one debut, spending four weeks atop the chart, and achieved various chart feats in Australia, the UK and the US; in the latter, the tracks "Willow", "No Body, No Crime", and "Coney Island" impacted pop, country, and alternative radio stations, respectively. "Willow" became Swift's seventh Billboard Hot 100 number-one song and her second in 2020 after "Cardigan", making her the first ever act to simultaneously debut atop both Billboard 200 and Hot 100 charts two times. Evermore was 2021's best-selling alternative music album and Americana album in the US and the UK, respectively.
