Nalan Xingde (simplified Chinese: 纳兰性德; traditional Chinese: 納蘭性德; Wade–Giles: Na-lan Hsing-te; January 19, 1655 – July 1, 1685), Manchu name Nara Singde, courtesy name Rongruo (容若), was a Qing dynasty Chinese poet, famous for his ci poetry. He was born Nalan Chengde (納蘭成德), but had to change his name when the Kangxi Emperor named Yunreng his crown prince. The character cheng (成) became taboo because it was phonetic part of Yunreng's birth name. He died at the age of 30, due to an unspecified illness. One of the daughters of Nalan Xingde was married to Han Bannerman Nian Gengyao.
