"Have You Never Been Mellow" is a song recorded by British-Australian singer Olivia Newton-John for her 1975 fifth studio album of the same name. Written and produced by John Farrar, the song was released as the lead single from the album in January 1975. In the United States, the single became Newton-John's second consecutive number-one hit on the Billboard Hot 100, topping the chart in March 1975. It also topped the Adult Contemporary chart, and continued her success as a crossover artist when it peaked at number three on the Hot Country Songs chart. It also became her fourth consecutive single to receive a Gold certification by the Recording Industry Association of America (RIAA). The single also reached number one in Canada, and peaked at number ten in Newton-John's native Australia. "Have You Never Been Mellow" was nominated for Best Pop Vocal Performance, Female at the 18th Annual Grammy Awards, but lost to Janis Ian's "At Seventeen".
