Nalan Xingde (; January 19, 1655 – July 1, 1685), Manchu name Nara Singde, courtesy name Rongruo (), was a Chinese poet in Qing dynasty, 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.
Born in Beijing in January 1655, Nalan Xingde came from a powerful Manchu family that not only belonged to the Plain Yellow Banner of the Eight Banners, but was also related to royalty. His father Mingju, who became Grand Secretary in 1677, was second cousin to the Shunzhi Emperor, and his mother was the fifth daughter of Ajige, Prince Ying of the First Rank, and thus first cousin to the Shunzhi Emperor.
Xingde's genealogical origins could have been Mongolian, however, since his clan was originally a tribe of the Mongol Yehe who defeated the Manchu Nara tribe and adopted their name. He was reportedly a bright child with a talent in writing poetry and essays. Like all Manchu boys, however, he was also taught riding and archery, and was said to be quite proficient in both. By nineteen, he was already enjoying a literary reputation.
However, success at the national civil service examination eluded him until 1676, when he obtained the Chin-shih Degree. In contrast to the more common practice of naming a chin-shih a bureaucrat/official, the Kangxi Emperor gave Xingde a military position as a junior grade officer in the Imperial Bodyguard (三等侍衛).
