The Grudge (song)

"The Grudge" (stylized in all lowercase) is a song by American singer-songwriter Olivia Rodrigo from her second studio album, Guts (2023). Rodrigo wrote it with its producer, Dan Nigro. The song became available as the album's tenth track on September 8, 2023, when it was released by Geffen Records. A piano-driven power ballad, "The Grudge" details Rodrigo's regret and burnout after somebody she looked up to betrayed her trust. Critics varied in their interpretation of the song, with some interpreting its subject as the breakup of a romantic relationship while others believed it was about Rodrigo's relationship with Taylor Swift.

Some music critics were positive about the vulnerability, lyrics, and Rodrigo's vocal performance on "The Grudge", while others thought it was too melodramatic and self-centered. The song reached number six in Ireland and number 10 in New Zealand. It charted within the top 20 in Australia, Canada, and the United States and received a gold certification in Brazil and Canada. She included "The Grudge" on the set list of her 2024 concert tour, the Guts World Tour.
