In Chinese philosophy, the three teachings (Chinese: 三教; pinyin: sānjiào; Vietnamese: tam giáo, Chữ Hán: 三教; Indonesian: tridarma) are Confucianism, Taoism, and Buddhism. The learning and the understanding of the three teachings are traditionally considered to be a harmonious aggregate within Chinese culture. Literary references to the three teachings by prominent Chinese scholars date back to the 6th century. The term may also refer to a non-religious philosophical grounds of aggregation as exemplified within traditional Chinese medicine.

The phrase also appears as the three teachings harmonious as one (三教合一; sānjiào héyī). In common understanding, three teachings harmonious as one simply reflects the long history, mutual influence, and (at times) complementary teachings of the three belief systems.

It can also be used in reference to the Sanyi teaching, a syncretic sect which was founded during the Ming dynasty by Lin Zhao'en, wherein Confucian, Taoist, and Buddhist beliefs are combined according to their usefulness in self-cultivation. However, the phrase is not necessarily a reference to this sect.

While Confucianism was the ideology of the law, the institutions and the ruling class, Taoism was the worldview of the radical intellectuals and it was also compatible with the spiritual beliefs of the peasants and the artisans. The two, although opposite ends of the philosophical spectrum, jointly created the Chinese "image of the world".

The joint worship of the three teachings can be found in some Chinese temples, such as in Hanging Temple.

Believers of the concept think that "three teachings are ... safer than one" and that using elements from all three brings good fortune.

Confucianism is a complex school of thought, sometimes also referred to as a religion, revolving around the principles of the Chinese philosopher Confucius. It was developed in the Spring and Autumn period during the Zhou dynasty. The main concepts of this philosophy include ren (humaneness), yi (righteousness), li (propriety/etiquette), zhong (loyalty), and xiao (filial piety), along with strict adherence to social roles. This is illustrated through the five main relationships Confucius interpreted to be the core of society: ruler-subject, father-son, husband-wife, elder brother-younger brother, and friend-friend. In these bonds, the latter must pay respect to and serve the former, while the former is bound to care for the latter.

The following quotation is from the Analects, a compilation of Confucius' sayings and teachings, written after his death by his disciples.
