Ekin Cheng Yee-Kin / 鄭伊健 (born October 4, 1967) is a Hong Kong actor and Cantopop singer. Earlier in his career he was known as Noodle Cheng (鄭伊麵), though he has now reverted to a more conventional-sounding first name. Sometimes he uses Dior (because that was what it sounded like when his younger sister tried to call him) as a first name but usually Ekin is the name used.

Ekin had a successful music career with BMG. But in the 2000s, he signed with EEG, a juggernaut company owned by Albert Yeung. Under this company he was 'frozen' and not allowed to put out any records. But as is a custom with EEG, he made several movies with other EEG stars. As of 2004, his contract with EEG ended and he returned to BMG where he is once again releasing records. Read more on Last.fm.
