Yen-j (Chinese:嚴爵; Jyutping: jim4 zoek3; Pe̍h-ōe-jī: Giâm Chiok; Pha̍k-fa-sṳ: Nyâm Tsiok; born 23 April 1988) is a Taiwanese jazz-pop singer-songwriter and actor.

He has achieved rising success as a newcomer on the Mandopop scene, due to testimonials from well-known artists such as Wang Leehom,[1] Mayday's Ashin, Dee Hsu, Darkie Chen and DJ Tai Mai Shu.

[2] Yen-J who comes from a family of doctors, was given a deadline of two years to start off his music career by his father, who wanted him to study medicine.

In January 2010, he released an EP, Trapped in Taipei (困在台北, Kùn Zài Táiběi) and went on various live gigs around Taiwan to be able to get used to performing by himself, and to raise audience awareness.

Yen-J has also received much interest towards his music from providing songs for some drama soundtracks, such as Queen Of No Marriage (敗犬女王), P.S Man (偷心大聖PS男) as well as the popular Autumn's Concerto (下一站,幸福), which featured some of his songs, such as "拓也的秘密心願 – 我以為" (I Presumed – secret version) and "相遇就不放手" (Not Letting Go).

His idols include Wang Leehom, Khalil Fong, Jay Chou and Stevie Wonder, who he hopes to be able to sound like in 5 years’ time.
