"Nothing's Gonna Stop Us Now" is a song co-written by Diane Warren and Albert Hammond and recorded by American rock band Starship for their second studio album, No Protection (1987). It’s a power ballad duet featuring vocalists Grace Slick and Mickey Thomas and the theme to the 1987 romantic-comedy film Mannequin.
The song reached number one on the US Billboard Hot 100, Warren's first single to do so. Elsewhere, "Nothing's Gonna Stop Us Now" topped the charts in Canada, Ireland and the United Kingdom, where it became the second-best-selling song of 1987. "Nothing's Gonna Stop Us Now" received a nomination for Best Original Song at the 60th Academy Awards. A Cantonese cover, zh:敢爱敢做 by singer George Lam, briefly topped the Hong Kong charts.
The song's co-writer Albert Hammond has recorded his own version on three occasions: the first in 1989 for his Best of Me album, in 2010 as a duet with Bonnie Tyler on the album Legend, and then in 2014 as an orchestral version on the album In Symphony. The song was used as the trailer and end credits song for the Marvel Cinematic Universe film Thunderbolts* (2025).
