Vanessa Joy Amorosi (born 8 August 1981) is an Australian singer-songwriter and recording artist. Her combined album and single sales have reached over two million worldwide.

Amorosi rose to fame in 1999 with the release of her debut single, "Have a Look", which reached gold status in Australia. The following year, she achieved international success with her debut studio album, The Power. She performed at both the 2000 Olympic Games opening ceremony and its accompanying closing ceremony in Sydney. Her performance of "Heroes Live Forever" at the opening ceremony gained international acclaim. Performed at the closing ceremony, "Absolutely Everybody", which became an unofficial anthem of the games, went on to be a major hit in Australia and many European countries including the United Kingdom and Germany. After a second studio album, Change, in 2002 and several years from the spotlight, Amorosi returned in 2008 with the release of her third studio album Somewhere in the Real World. The album's most successful single, "Perfect", marked her comeback to the ARIA top 5 singles and was the most played Australian song on Australian radio for 2008. Her fourth studio album, Hazardous, followed in 2009 and is Amorosi's second-best selling album in Australia behind her debut, The Power. It produced her first number one-charting single, "This Is Who I Am".

She subsequently released three more albums: Back to Love (2019), Blacklisted Collection (2020) and City of Angels (2022).

To date Amorosi has received a total of 16 ARIA and APRA nominations. She has won an APRA award with "Shine", a VIVA Comet Award for "Best International Newcomer" and an ARIA No.1 Chart Award with "This Is Who I Am".
