Renée Rebecca Geyer (born 11 September 1953, Melbourne, Victoria, Australia) is an Australian singer who has long been regarded as one of the finest exponents of jazz, soul and R&B idioms. She had commercial success as a solo artist in Australia, with "It's a Man's Man's World", "Heading in the Right Direction" and "Stares and Whispers" in the 1970s and "Say I Love You" in the 1980s. Geyer has also been an internationally respected and sought-after backing vocalist, whose session credits include work with Sting, Chaka Khan, Toni Childs and Joe Cocker.

In 2000, her autobiography, Confessions of a Difficult Woman, co-written with music journalist Ed Nimmervoll, was published. In her candid book, Geyer detailed her drug addictions, sex life and career in music. She described herself as "a white Hungarian Jew from Australia sounding like a 65-year-old black man from Alabama". She spent more than ten years based in the United States but had little chart success there. Geyer returned to Australia in the mid-1990s and her career has continued into the 21st century with her 2003 album, Tenderland, which peaked at #11 on the ARIA albums charts.
