Chinese New Year is a Chinese festival that celebrates the beginning of a new year on the traditional Chinese calendar. The festival is usually referred to as the Spring Festival in modern China, and is one of several Lunar New Years in Asia. Observances traditionally take place from the evening preceding the first day of the year to the Lantern Festival, held on the 15th day of the year. The first day of Chinese New Year begins on the new moon that appears between 21 January and 20 February. In 2019, the first day of the Lunar New Year will be on Tuesday, 5 February, initiating the Year of the pig.

Chinese New Year is one of the world's most prominent and celebrated festivals, and is the cause of the largest annual mass human migration in the world.

Chinese New Year is associated with several myths and customs. The festival was traditionally a time to honor deities as well as ancestors. Within China, regional customs and traditions concerning the celebration of the New Year vary widely, and the evening preceding Chinese New Year's Day is frequently regarded as an occasion for Chinese families to gather for the annual reunion dinner. It is also traditional for every family to thoroughly clean their house, in order to sweep away any ill-fortune and to make way for incoming good luck. Another custom is the decoration of windows and doors with red paper-cuts and couplets. Popular themes among these paper-cuts and couplets include that of good fortune or happiness, wealth, and longevity. Other activities include lighting firecrackers and giving money in red paper envelopes. For the northern regions of China, dumplings are featured prominently in meals celebrating the festival.
