The richness of Vietnam's origins is evident throughout its culture. Spiritual life in Vietnam is a grand panoply of belief systems, including Confucianism, Taoism, Buddhism, Christianity, and Tam Giao (literally 'triple religion'), which is a blend of Taoism, popular Chinese beliefs, and ancient Vietnamese animism.

The most important festival of the year is Tet, a week-long event in late January or early February that heralds the new lunar year and the advent of spring. Celebration consists of both raucous festivity (fireworks, drums, gongs) and quiet meditation. In addition to Tet, there are about twenty other traditional and religious festivals each year.

Vietnamese architecture expresses a graceful aesthetic of natural balance and harmony that is evident in any of the country's vast numbers of historic temples and monasteries. The pre-eminent architectural form is the pagoda, a tower comprised of a series of stepped pyramidal structures and frequently adorned with lavish carvings and painted ornamentation. Generally speaking, the pagoda form symbolizes the human desire to bridge the gap between the constraints of earthly existence and the perfection of heavenly forces. Pagodas are found in every province of Vietnam.

As a language, Vietnamese is exceptionally flexible and lyrical, and poetry plays a strong role in both literature and the performing arts. Folk art, which flourished before French colonization, has experienced resurgence in beautiful woodcuts, village painting, and block printing. Vietnamese lacquer art, another traditional medium, is commonly held to be the most original and sophisticated in the world. Music, dance, and puppetry, including the uniquely Vietnamese water puppetry, are also mainstays of the country's culture.

Although rice is the foundation of the Vietnamese diet, the country's cuisine is anything but bland. Deeply influenced by the national cuisines of France, China, and Thailand, Vietnamese cooking is highly innovative and makes extensive use of fresh herbs, including lemon grass, basil, coriander, parsley, laksa leaf, lime, and chili. Soup is served at almost every meal, and snacks include spring rolls and rice pancakes. The national condiment is nuoc mam, a piquant fermented fish sauce served with every meal. Indigenous tropical fruits include bananas, pineapples, coconuts, lychees, melons, mandarin oranges, grapes, and exotic varieties like the three-seeded cherry and the green dragon fruit.
