"Ain't No Stoppin' Us Now" is a 1979 disco song performed by R&B duo McFadden & Whitehead, from their debut album McFadden & Whitehead. They wrote and produced the song along with keyboard player Jerry Cohen. Released as the lead single from the album, the song spent a week at number one on the R&B singles chart. It also proved to be a successful crossover hit, peaking at number thirteen on the Billboard Hot 100, and reached number 5 in the UK. The single also made it to number ten on the disco charts. It eventually went double platinum, selling over 2 million copies.

"Ain't No Stopping Us Now" is about succeeding despite having faced previous disadvantages ("so many things that held us down"). It was widely interpreted to be about the experience of the African American community, and after attaining popularity, became referred to as "the new black national anthem" (the original being the 1900 song "Lift Every Voice and Sing").

McFadden & Whitehead would revisit the song in their 1984 single "Ain't No Stoppin' (Ain't No Way)."

Despite being seen as social commentary, in an interview conducted by Philadelphia video producer Bob Lott, John and Gene revealed that the song was actually about their frustration with Philadelphia International Records owners Kenny Gamble and Leon Huff, who for many years preferred that they remain as house songwriters and not performers. Gamble has confirmed that upon first hearing "Ain't No Stoppin' Us Now", he tried unsuccessfully to convince McFadden and Whitehead to give the song to The O'Jays, as he felt it was better to write and produce for the prominent recording artists of the day than to try to compete with them as on-stage performers.

The bass hook was played by Philadelphia International Records house musician Jimmy Williams.
