Rita Chao (11 March 1950 – July 2014), also known as Ling Yun (Chinese: 凌雲), was a Singaporean former singer and actress.

[8][4] In 1975, Chao sang "Majulah Singapura" alongside Milah Hussain, Sylvia McCully, Kala Puspanathan, and Chong Hoon Sing for a presentation at the ASEAN Exchange Concert in Bangkok.

[9][10] In March 1978, Chao starred, alongside six other Singaporean musicians, on Taiwanese variety programme Big Screen.

This inclusion of Singaporean singers in Taiwanese programming was stated to be "an unexpected departure from the ordinary" and "could be interpreted as a compliment to Singapore.

She lived in a Housing and Development Board flat with her mother in Yishun and described her current job as "very simple" and that it pays "a few hundred dollars and it's enough for me".

Her death was only announced in 2015 by her mother on Lianhe Zaobao because "the family did not inform show business friends as they wanted the past to be forgotten".
