The Downliners Sect are a British rhythm and blues band of the beat boom era, formed in 1963 when the existing Downliners band split up.

Stylistically, they were similar to The Yardbirds, The Pretty Things and the Rolling Stones, playing basic R&B on their first album The Sect. Critic Richie Unterberger wrote: "The Sect didn't as much interpret the sound of Chess Records as attack it, with a finesse that made the Pretty Things seem positively suave in comparison."
