Jacky Cheung (born 10 July 1961) is a Hong Kong singer-songwriter and actor. The Chinese language media refers to him, Aaron Kwok, Andy Lau and Leon Lai as the Cantopop Four Heavenly Kings (四大天王), with more than 60 million records sold as of 2000.

Cheung is known for his baritone voice. On 15 February 1996 in London, he married Hong Kong actress May Lo Mei-mei, with whom he has two daughters. Cheung is also nicknamed "god of Songs" (歌神), but he is the second person to hold this title, after former Cantopop singer Sam Hui. In an interview with Ray Cordeiro (Uncle Ray), Cheung stated that the title was more appropriate for Hui than for him, since he actually wrote and popularized songs.

Cheung originally started working as a reservation officer for the Cathay Pacific airline. His music career started when he won the Amateur 18-Hong Kong district singing contest in 1984 with the song Fatherland (大地恩情). He ousted more than 10,000 other contestants. After winning the contest, he was signed by the then Polygram Records, now Universal Music Group. Although encouraged by a bright start, he was not able to achieve immediate supremacy in Cantopop, then dominated by Leslie Cheung, Alan Tam, Anita Mui and Danny Chan. In 1985 he won his first two major awards together with the 1985 RTHK Top 10 Gold Songs Awards and the 1985 Jade Solid Gold Top 10 Awards.
