The Mid-Autumn Festival (traditional Chinese: 中秋節; simplified Chinese: 中秋节; Vietnamese: tết Trung Thu) is a harvest festival celebrated by ethnic Chinese and Vietnamese people. The festival is held on the 15th day of the 8th month of the lunar calendar with full moon at night, corresponding to late September to early October of the Gregorian calendar with full moon at night.

Mainland China listed the festival as an "intangible cultural heritage" in 2006 and a public holiday in 2008. It is also a public holiday in Taiwan and in Hong Kong. In the Vietnamese culture, it is considered the second-most important holiday tradition after Tết.

Due to China's influence, Mid-Autumn Festival is also celebrated in other parts of Asia. Mooncakes have also appeared in western countries as a form of delicacy.

The Mid-Autumn Festival is also known by other names, such as:

The festival celebrates three fundamental concepts which are closely tied to one another:

Traditions and myths surrounding the festival are formed around these three concepts, although traditions have changed over time due to changes in technology, science, economy, culture, and religion. It's about well being together.

The Chinese have celebrated the harvest during the autumn full moon since the Shang dynasty (c. 1600–1046 BCE). Morris Berkowitz, who studied the Hakka people during the 1960s, theorizes that the harvest celebration originally began with worshiping Mountain Gods after the harvest was completed. For the Baiyue peoples, the harvest time commemorated the dragon who brought rain for the crops. The celebration as a festival only started to gain popularity during the early Tang dynasty (618–907 CE). One legend explains that Emperor Xuanzong of Tang started to hold formal celebrations in his palace after having explored the Moon-Palace. The term mid-autumn (中秋) first appeared in Rites of Zhou, a written collection of rituals of the Western Zhou dynasty (1046–771 BCE).
