The Battle of Cầu Giấy or Paper Bridge, fought on 19 May 1883, was one of the numerous clashes during the Tonkin Campaign (1883–86) between the French and the Black Flags. A small French force under the command of capitaine de vaisseau Henri Rivière attacked a strong Black Flag defensive position near the village of Cầu Giấy a few miles to the west of Hanoi, known to the French as Paper Bridge (Pont de Papier). After initial successes, the French were eventually enveloped on both wings, and were only with difficulty able to regroup and fall back to Hanoi. Rivière and several other senior officers were killed in the action.

French interest in northern Vietnam dated from the 1860s, when France annexed several southern provinces of Vietnam to become the colony of Cochinchina, laying the foundations for its later colonial empire in Indochina. French explorers followed the course of the Red River through northern Vietnam to its source in Yunnan, arousing hopes that a profitable overland trade route could be established with China, bypassing the treaty ports of the Chinese coastal provinces. The main obstacle to the realisation of this dream was the Black Flag Army, a well-organized bandit force under a formidable leader, Liu Yongfu (Liu Yung-fu, 劉永福), which was levying exorbitant dues on trade on the Red River between Sơn Tây and the town of Lào Cai on the Yunnan border.

French intervention in northern Vietnam was precipitated by Commandant Henri Rivière, who was sent with a small French military force to Hanoi at the end of 1881 to investigate Vietnamese complaints against the activities of French merchants. In defiance of the instructions of his superiors, Rivière stormed the citadel of Hanoi on 25 April 1882. Although Rivière subsequently returned the citadel to Vietnamese control, his recourse to force was greeted with alarm in both Vietnam and China.

The Vietnamese government, unable to confront Rivière with its own ramshackle army, enlisted the help of Liu Yongfu, whose well-trained and seasoned Black Flag soldiers were to prove a thorn in the side of the French. The Black Flags had already inflicted one humiliating defeat on a French force commanded by lieutenant de vaisseau Francis Garnier in 1873. Like Rivière in 1882, Garnier had exceeded his instructions and attempted to intervene militarily in northern Vietnam. Liu Yongfu had been called in by the Vietnamese government, and ended a remarkable series of French victories against the Vietnamese by defeating Garnier’s small French force beneath the walls of Hanoi. Garnier was killed in this battle, and the French government later disavowed his expedition.
