The Việt Nam Quốc Dân Đảng, abbreviated VNQDĐ or Việt Quốc, was a nationalist and democratic socialist political party that sought independence from French colonial rule in Vietnam during the early 20th century. Its origins lie in a group of young Hanoi-based intellectuals who began publishing revolutionary material in the mid-1920s. In 1927, after the publishing house failed because of French harassment and censorship, the VNQDĐ was formed under the leadership of Nguyễn Thái Học. Modelling itself on the Kuomintang of Nationalist China the VNQDĐ gained a small following among northerners, particularly teachers and intellectuals. The party, which was less successful among peasants and industrial workers, was organised in small clandestine cells.

Vietnamese nationalism is a form of nationalism that asserts the Vietnamese people as a separate independent nation. It encompasses a broad range of ideas and sentiments harbored by the Vietnamese people in regards with national identity.
