Founded in 1983, the Hong Kong Composers' Guild (HKCG) is a professional association of serious composers with objectives to promote and cultivate music composition in Hong Kong. Apart from organising concerts, publishing scores and producing recordings of works by Hong Kong composers, HKCG also takes an active part in arousing interest in composition especially amongst youths and in developing music as a vital creative art form in Hong Kong.

Organising composition competitions and sending composers to the community and schools are its regular activities. HKCG works closely with professional musicians and institutions in not just concert performances, but orchestration workshops, field trips, forum, commissions, and community services. As one of the cultural ambassadors of our city, HKCG has also established strong links with many international organisations and has played a significant role in international music exchanges.

HKCG's predecessor is the Hong Kong Section of the Asian Composers League which was founded in 1973. HKCG is also a National Section of the International Society for Contemporary Music. It also co-operates with RTHK to send a composer as representative to the International Rostrum of Composers each year. Since July 2010, HKCG has become one of the Year Grantees of the Hong Kong Arts Development Council.
