Xie Shaoguang (谢韶光), also known as Cha Shao-Kwong, is a Singaporean retired actor. He is best known for acting in many Chinese-language television series produced by MediaCorp Channel 8. He was prominently a full-time Mediacorp artiste from 1985 to 2005.

Since the start of his acting career in 1989 in the television series A Mother's Love (亲心唤我心), Xie has received numerous accolades, including winning the Star Awards Best Actor award five times and the Best Supporting Actor award twice since the ceremony's inception in 1994. In 2005, he was awarded the All-Time Favourite Artiste award, in recognition of his career after winning the Top 10 Most Popular Male Artistes award from 1995-2004 respectively with Fann Wong. One of his most notable roles is the Chinese folk deity Ji Gong in the 1997 television series The Legends of Jigong.

In 2005, Xie formalised his plans to retire from the entertainment industry when he decided not to renew his contract which expired in September the same year, although his intention to quit has been made known years earlier. He said that after retirement, he would be living in Malaysia, where he planned to open a refuge for stray dogs and cats. His final appearance in the media was in the television series Baby Blues, which ended its run on 9 September 2005.

Since leaving the entertainment industry, Xie has rejected all requests to appear in public events or on screen, including an invitation by Singaporean director Anthony Chen to star in the award-winning film Ilo Ilo.

Xie currently resides in Permas Jaya, Malaysia, where he was ordained a monk in 2013. In 2016, Singaporean media reports say Xie has given up his vows as a monk and returned to his job as a chef in a vegetarian restaurant.

After a 12-year hiatus, Xie made an official media appearance on 14 October 2017. He had returned to MediaCorp to conduct acting classes for younger actors. Xie has stated he would return to acting, if there is a role that can persuade him to do so.
