The Kiều Thạc Nhu's invasion of the Rideva Empire, also known as Kiều Thạc Nhu's Campaigns Against the Rideva Empire and the First Kiếm Hoà-Rideva War, was a military action launched by Kiều Thạc Nhu in 1288 and lasted until 1294. It was the longest campaign of Nhu's military career, and resulted in the dynasty gaining more land and territories for Quenminese settlers to inhabit in, and proliferate Quenminese culture throughout. The invasion also saw the first conventional usage of the hand cannon by the Quenminese.

Nhu made the decision to expand the Kiếm Hoà Dynasty's territories into Tennai after receiving information about the weakening political standing of the Rideva Empire, as well as its lush resources. On 14 May 1288, sensing an opportunity to exert the dynasty's rule over the destabilizing realm, Nhu gathered an army totaling 500,000 with foreign contingents from Chamia, Arantho Kingdom and the Töbedar Khanate, and crossed onto the northern territories on 19 June. After the success of the campaign, Nhu ensured that all troops were paid fairly.

The campaign was dramatized in literature and film, such as the Quenminese novels Ballad of the Black Tigress alongside its famous theatrical adaptation; the poems A Mournful Death in War and Nhu and Rudrani; the Quenminese historical series The Black Tigress; and the Tennaiite historical movie Dance of Queens.
