Sammul Chan Kin-Fung (陳鍵鋒) is a Hong Kong, actor, singer, and presenter. Chan debuted in 1999 as a DJ for Metro Broadcast Corporation Limited under his birth name, although most of the time he was simply referred to and credited as simply "Sammul". From 1999, he has signed with three record labels to release albums, but all were not successful. He recorded a full-length Mandarin album in Taiwan, but the label failed.

In 1999, after signing a management contract with Ivy Entertainment and a filming contract with TVB, he began to officially use the Chinese stage name Chan Kin-fung and began filming television dramas. He later gained recognition as the ambitious young lawyer Vincent in the 2003 TVB drama "Survivor's Law" and received further popularity the same year through his role as Donald in "Triumph in the Skies", a ratings hit.
