Roger Kwok Chun-on (Chinese: 郭晋安) is a Hong Kong television actor and former singer, who works for the TV station TVB.

Kwok was born in Hong Kong, and his native family roots are in Zhongshan, Guangdong.

Roger Kwok has worked for TVB for many years, and received moderate fame in dramas such as Detective Investigation Files IV (1999), At the Threshold of an Era (1999-2000) and Law Enforcers (2002), but it was not until he played the role of the low-IQ Ding Sheung Wong (丁常旺) in the hugely popular drama Square Pegs (2002-2003) did he reach stardom, and went on to win Best Actor at the 2003 TVB Anniversary Awards.

After appearing in the moderately popular dramas Not Just a Pretty Face (美麗在望) (2003) and To Get Unstuck in Time (2004), Kwok reprised his role as Wong in the modernized version of Square Pegs, Life Made Simple, in 2005, which again was a huge success.

In December 2014, Kwok won his third Best Actor Award for another villainous role, this time as the barrister "Matt" Ko Chit Hang in the drama Black Heart White Soul.
