Ronglu (6 April 1836 – 11 April 1903), courtesy name Zhonghua, was a Manchu political and military leader of the late Qing dynasty. He was born in the Guwalgiya clan, which was under the Plain White Banner of the Manchu Eight Banners. Deeply favoured by Empress Dowager Cixi, he served in a number of important civil and military positions in the Qing government, including the Zongli Yamen, Grand Council, Grand Secretary, Viceroy of Zhili, Beiyang Trade Minister, Secretary of Defence, Nine Gates Infantry Commander, and Wuwei Corps Commander. He was also the maternal grandfather of Puyi, the last Emperor of China and the Qing dynasty.

Ronglu was born in the Manchu Guwalgiya clan, which was under the Plain White Banner of the Manchu Eight Banners. His grandfather, Tasiha (塔斯哈), served as an Imperial Resident in Kashgar. His father, Changshou (長壽), was a zongbing (總兵; a military commander).

Ronglu was a yinsheng (蔭生), a type of position awarded to civil service candidates who successfully gained admission to the Guozijian (Imperial Academy). He started his career in the Ministry of Works as a yuanwailang (員外郎; assistant director) and was tasked with constructing roads in Zhili Province.

In the early years of the Tongzhi Emperor's reign (early 1860s), he set up the Firearms Division and was rewarded with the position of a jingtang (京堂; fifth-grade magistrate). He was also appointed as a flank commander (翼長) and zhuancao dachen (專操大臣) before being transferred to be a zongbing (總兵) of the left flank. Through Wenxiang's recommendation, he became the Vice Secretary (侍郎) of the Ministry of Works. Later, he was reassigned to the Ministry of Revenue and concurrently appointed as Minister of the Imperial Household Department.

The Tongzhi Emperor died in 1875 and was succeeded by his cousin, the Guangxu Emperor. In the same year, Ronglu became an infantry commander (步軍統領). Three years later, he was reassigned to be a Left Censor-in-Chief (左都御史) and Secretary of Works. In 1878, Baoting (寶廷) wrote a memorial to the imperial court, pointing out that certain officials concurrently held too many appointments, hence Ronglu was relieved of his duties as Secretary of Works and Minister of the Imperial Household Department.

Ronglu was initially accused of accepting bribes and was demoted by two grades. He also offended Prince Chun, Baojun (寶鋆) and Shen Guifen (沈桂芬) and was forced to retire in early 1879. However, in 1891, he was restored to the civil service and appointed as General of Xi'an.

In 1894, Ronglu was recalled from Xi'an to the capital Beijing to attend Empress Dowager Cixi's birthday celebrations. He was appointed again as an infantry commander (步軍統領). During the First Sino-Japanese War of 1894–1895, Ronglu, along with Prince Gong and Prince Qing, were in charge of military affairs. After the Qing and Japanese empires reached a peace settlement, Ronglu nominated Yuan Shikai to oversee the creation and training of the New Army.

In 1896, Ronglu was appointed as Secretary of Defence and Assistant Grand Secretary (協辦大學士). He also proposed transferring Dong Fuxiang and his Gansu Army to Beijing to defend the capital and enhance the training of the New Army.
