Adèle Anderson (born 14 June 1952) is an English singer and actress, and one third of the cabaret group Fascinating Aïda. In 1995, with Fascinating Aïda, she was nominated for the Laurence Olivier Award for Best Entertainment.

Anderson has appeared internationally in concerts, in theatrical plays, and on the BBC Television programme Gemma Masters. In addition, sometimes with Dillie Keane, Anderson writes lyrics to most of Fascinating Aïda's songs and has contributed to the songs of several hit musicals, including The Challenge (Shaw Theatre) and The Ten Commandments (The Place).

Anderson joined Fascinating Aïda in 1984, a year after its inception, and has performed with them ever since. In 2014, they recorded the show Charm Offensive, which they toured nationwide.

Anderson is a transgender woman. She had gender affirming surgery after graduating from Birmingham University, as part of her medical transition. She completed her social transition some time before speaking publicly about being transgender.

Her career history includes working as a civil servant and a secretary, before later becoming a jazz singer.

She is a patron of Humanists UK (formerly known as the British Humanist Association). She later became a humanist celebrant for Humanists UK, specialising in non-religious weddings.

On 15 September 2010, Anderson, along with 54 other public figures, signed an open letter published in The Guardian, stating their opposition to Pope Benedict XVI's state visit to the UK.
