"Your Power" is a song by American singer-songwriter Billie Eilish. She wrote the song with her brother Finneas O'Connell, who handled its production.
A folk ballad accompanied by an acoustic guitar, "Your Power" is a plea for people to stop abusing their authority, mainly towards vulnerable women. Darkroom and Interscope Records released the song as the third single from Eilish's second studio album, Happier Than Ever (2021), on April 29, 2021.
"Your Power" received positive reviews from music critics, who praised its subject matter. In the US, the song debuted at its peak position of number 10 on the Billboard Hot 100: the highest chart entry during that week. "Your Power" reached the top 10 in singles charts for 20 other countries, including the UK where it received a silver certification. It peaked at number 6 on the Billboard Global 200.
Eilish directed the music video for "Your Power", which premiered on the same day as the song's release. In it, she sings alone at the Simi Valley; during this, an anaconda wraps itself around her.
Eilish revealed the first live rendition of the song in The Late Show with Stephen Colbert and included it in the set lists of a concert film and a world tour in support of Happier Than Ever.
She also performed "Your Power" as part of political causes, such as in protest against the US Supreme Court decision to overturn Roe v. Wade.
