Taoism has many followers in Hong Kong. Taoist Day, the birthday of Lao Zi, is celebrated on the 15th day of the second month of the lunar year.

Taoist gods are classified under two headings: Prior Heavens, and Posterior Heavens. The gods commonly worshipped by Taoists as patron spirits are those of the Prior Heavens, including Senior Lord Taishang, Jade Emperor and Doumu (Mother of the Dipper). Mortal gods of the Posterior Heavens group, such as Lui Cho, Kwan Tai and Che Kung, are revered for their great virtues and feats in saving mankind. Tin Hau, the Queen of Heaven and Protector of Seafarers, is worshipped widely, particularly during the Tin Hau Festival, which falls on the 23rd day of the third month in the lunar calendar. Worshippers pay homage at the famous Tin Hau Temple at Joss House Bay on the Clear Water Bay Peninsula on that day. Other leading deities include Pak Tai (Supreme Emperor of the Dark Heaven and local patron of Cheung Chau Island) and Hung Shing (God of the South Seas and a weather prophet).

Notable temples include the Wong Tai Sin Temple, named after a Taoist deity, in the Wong Tai Sin District of Kowloon, the Che Kung Temple in Sha Tin in the New Territories, and the Man Mo Temple in Hollywood Road on Hong Kong Island.
