The Qingming festival or Ching Ming Festival, also known as Tomb-Sweeping Day in English (sometimes also called Chinese Memorial Day or Ancestors' Day), is a traditional Chinese festival observed by the Han Chinese of mainland China, Hong Kong, and Macau, and by the ethnic Chinese of Taiwan, Malaysia, Singapore, Cambodia, Indonesia, Philippines, Thailand, Vietnam and Panama. It falls on the first day of the fifth solar term of the traditional Chinese lunisolar calendar. This makes it the 15th day after the Spring Equinox, either 4, 5 or 6 April in a given year. During Qingming, Chinese families visit the tombs of their ancestors to clean the gravesites, pray to their ancestors and make ritual offerings. Offerings would typically include traditional food dishes and the burning of joss sticks and joss paper. The holiday recognizes the traditional reverence of one's ancestors in Chinese culture.

The Qingming Festival has been observed by the Chinese for over 2500 years, although the observance has changed significantly. It became a public holiday in mainland China in 2008, where it is associated with the consumption of qingtuan, green dumplings made of glutinous rice and Chinese mugwort or barley grass.

In Taiwan, the public holiday was in the past observed on 5 April to honor the death of Chiang Kai-shek on that day in 1975, but with Chiang's popularity waning, this convention is not being observed. A confection called caozaiguo or shuchuguo, made with Jersey cudweed, is consumed there.

A similar holiday is observed in the Ryukyu Islands, called Shīmī in the local language.
