Vietnam is a diverse religion and belief country. Because of the development of Vietnamese society and the exchange of foreign civilization, Vietnam religion still develops yet keeps the origin of traditional folk religion which is old and plays a crucial role in local people’s spiritual life. Derived from the cult of nature, the folk religion allows people worship the huge number of Gods including Nature Gods such as Sun, Moon, Mountain, River and Forest; Tutelary Gods in Communal House at Vietnamese village and Ancestor worship.

In front of the entering of exotic religions, the Vietnamese did not receive them passively, but always modified closer to their indigenous religion ideology. Today, some follow a specific religion such as Christianity, Cao Dai, Hoa Hao, Hinduism and Islam but most of the rest believe they are non-religion. They all send their belief to a religion (often Buddhism and Confucianism) which makes their soul peaceful, satisfied or meet their spiritual needs. As a result, Vietnamese religion is unique and complex.
