A triad is one of many branches of Chinese transnational organized crime organizations based in the PRC, Hong Kong, Macau, Taiwan and also in countries with significant Chinese populations, such as the United States, Canada, Vietnam, Korea, Japan, Singapore, Philippines, Indonesia, Malaysia, Thailand, the United Kingdom, Belgium, Netherlands, France, Spain, South Africa, Australia and New Zealand.

According to the Oxford English Dictionary, 'triad' is a translation of the Chinese term 'San Ho Hui', or Triple Union Society, referring to the union of Heaven, Earth, and Man.

Another theory assumes that the term "Triad" was coined by British authorities in colonial Hong Kong, as a reference to the triads' use of triangular imagery. While never proven, it has been speculated that triad organizations either took after, or were originally part of revolutionary movements such as the White Lotus Society, the Taiping Rebellion, the Boxer Rebellion, and the Heaven and Earth Society.
