"One Love/People Get Ready" is a reggae song by Bob Marley & The Wailers from their 1977 album Exodus. It was first recorded in a ska style by Marley's original group, The Wailers, on their 1965 debut album The Wailing Wailers, and a heavily reworked version was included on African Herbsman under the name "All in One". A classic Bob Marley & The Wailers song, it has been included on many of their compilation albums. The song contains an interpolation of The Impressions' song "People Get Ready" written by Curtis Mayfield. Marley's hybrid version is titled, "One Love/People Get Ready," and it gives co-authorship credits to both Marley and Mayfield.

There is also a recent movie by that name.
