Louis Cha Leung-yung,  (born February 6 1924), better known by his pen name Jin Yong, is a Chinese novelist and essayist who co-founded the Hong Kong daily newspaper Ming Pao in 1959 and served as the newspaper's first editor-in-chief.

His fictional novels of the wuxia ("martial arts and chivalry") genre, have a widespread following in many Chinese-speaking areas, including Hong Kong, China, Taiwan, Southeast Asia, and the United States. His 15 works written between 1955 and 1972 earned him a reputation as one of the greatest and most popular wuxia writers ever. He is currently the best-selling Chinese author alive, and over 100 million copies of his works have been sold worldwide (not including an unknown number of pirated copies).

His works have been translated into many languages including English, French, Korean, Japanese, Vietnamese, Thai, Burmese, Malay and Indonesian. He has many fans outside of Chinese-speaking areas, as a result of the numerous adaptations of his works into films, television series, comics and video games.
