Prince Jingjin of the First Rank, or simply Prince Jingjin, was the title of a princely peerage used in China during the Manchu-led Qing dynasty (1644–1912).

The first bearer of the title was Nikan (1610–1652), the third son of Cuyen and a grandson of Nurhaci (the founder of the Qing dynasty). In 1648, Nikan was granted the title "Prince Jingjin of the Second Rank" by the Shunzhi Emperor. One year later, Nikan was promoted to "Prince Jingjin of the First Rank". In 1669, Lanbu (1642–1679), the third holder of the Prince Jingjin title, was demoted by the Kangxi Emperor from a qinwang (first-rank prince) to a feng'en zhenguo gong. The peerage de facto ended in 1680 when the Kangxi Emperor ordered Lanbu to be posthumously removed from the peerage.
