The Thousand Character Classic, also known as the Thousand Character Text, is a Chinese poem that has been used as a primer for teaching Chinese characters to children from the sixth century onward. It contains exactly one thousand characters, each used only once, arranged into 250 lines of four characters apiece and grouped into four line rhyming stanzas to make it easy to memorize. It is sung, much as children learning the Latin alphabet sing an "alphabet song." Along with the Three Character Classic and the Hundred Family Surnames, it has formed the basis of literacy training in traditional China.

Chinese characters are logographs used to write the Chinese languages and others from regions historically influenced by Chinese culture. Chinese characters have a documented history spanning over three millennia, representing one of the four independent inventions of writing accepted by scholars; of these, they comprise the only writing system continuously used since its invention. Over time, the function, style, and means of writing characters have evolved greatly. Informed by a long tradition of lexicography, modern states using Chinese characters have standardised their forms and pronunciations: broadly, simplified characters are used to write Chinese in mainland China, Singapore, and Malaysia, while traditional characters are used in Taiwan, Hong Kong, and Macau.
