Vietnamese calligraphy (Vietnamese alphabet: Thư pháp Việt Nam, chữ Hán: 書法越南) relates to the calligraphic traditions of Vietnam. It includes calligraphic works using a variety of scripts, including historical chữ Hán (Chinese characters), chữ Nôm (Vietnamese-derived characters), and the Latin-based Vietnamese alphabet. Historically, calligraphers used the former two scripts. However, due to the adoption of the Latin-based chữ Vietnamese alphabet, modern Vietnamese calligraphy also uses Latin script alongside chữ Hán Nôm.
Traditional Vietnamese calligraphy is strongly affected by that of China. Chữ Hán was often used as a literary language in ancient Vietnam, and as a result, Vietnamese calligraphy also used to follow Chinese calligraphy’s standard and used chữ Hán in many of its writings. For example, during the Lý dynasty, its style was similar to China’s Tang dynasty (618-907). During the Trần dynasty, it was influenced strongly by China’s Song (960-1279) and Yuan (1271-1368) dynasties.
