"Get Him Back!" (stylized in all lowercase) is a song by American singer-songwriter Olivia Rodrigo from her second studio album, Guts (2023). Rodrigo wrote the song with its producer, Dan Nigro. EMI Records released it as the album's third single on September 15, 2023. A rap rock, pop rap, and pop-punk song with influences of pop rock, "Get Him Back!" explores Rodrigo's desire to exact revenge on her ex-partner while simultaneously wanting to reconcile with him; the titular phrase conveys this through its double meaning.
