"You All Over Me" is a song by the American singer-songwriter Taylor Swift featuring harmony vocals from the American singer Maren Morris. Swift wrote the track with Scooter Carusoe in 2005 for her second studio album, Fearless (2008), but excluded it from the track-listing. She produced the song with Aaron Dessner for the album's 2021 re-recording, Fearless (Taylor's Version). "You All Over Me" was released for download via Swift's website on March 26, 2021.

A ballad that combines styles of Americana, country rock, and roots rock, "You All Over Me" has an acoustic and midtempo production. In the lyrics, a narrator is ruminating on a past romance that she cannot move on but ultimately accepts of what happened. The song received generally positive reviews from critics, who discussed the similarity to Fearless and praised the songwriting, production, and both artists performances. It peaked at number 35 on the Billboard Global 200 and reached the national charts of Australia, Canada, Ireland, the United Kingdom, and the United States. Swift performed "You All Over Me" with Morris during a Chicago concert as part of her Eras Tour (2023–2024).
