Anita Mui Yim-fong (Chinese: Mei Yan Fang ; Jyutping: Mui4 Jim6 Fong1; 10 October 1963 - 30 December 2003) was a Hong Kong singer and actress making major contributions to the Cantopop music scene and receiving numerous awards and honours.

On 5 September 2003, Mui publicly announced that she had cervical cancer, from which her sister had also died. She held a series of eight shows at the Hong Kong Coliseum from 6-11 November and 14-15 November 2003, which were to be her last concerts before her death.  Her symbolic act was to "marry the stage", which was accompanied by her hit song "Sunset Melody" (Xi Yang Zhi Ge ) as she exited the stage. The last song she performed on stage was "Cherish When We Meet Again" (Zhen Xi Zai Hui Shi ), a rendition of The Manhattans' "Let's Just Kiss And Say Goodbye" on 15 November 2003, where she was accompanied by her friends on the stage. She eventually succumbed to cervical cancer and died of respiratory complications leading to lung failure at Hong Kong Sanatorium and Hospital on 30 December 2003 at 02:50 (HK local time). She was 40 years old. Thousands of fans turned out for her funeral at North Point in January 2004.  In 1998, an ATV-produced television series Forever Love Song told a story of a character which was loosely based on that of Mui, but the character names were purposely changed. In 2007, a television series was produced in China titled Anita Mui Fei (Mei Yan Fang Fei ) to tell the story of her life. The 42-episode series was broadcast by China Education Television. Some subjects, such as her suffering from cancer, Leslie Cheung's suicide. and her mother's real estate dilemma, were avoided. Alice Chan (Chen Wei ) portrayed Mui in the series.  On 11 October 2008, a show on TVB, titled Our Anita Mui (Wo Men De Mei Yan Fang ), was dedicated to Mui. Many fans and off-stage personnel who worked with her had a chance to talk about their personal experiences with Mui. Singers who participated in the show included Andy Hui, Edmond Leung, and Stephanie Cheng. Mui was cremated and her ashes are interred at the Po Lin Monastery's mausoleum on Lantau Island.  On 18 July 2014, a statue of Anita Mui was unveiled on Hong Kong's Avenue of Stars.
