Nguyễn Chấn, known as Trần Văn Trà (September 15, 1919 – April 20, 1996) was a colonel-general in the People's Army of Vietnam.

During the days of The First Indochina War with the French, the Viet Minh recruited more than 600 defeated Japanese soldiers to fight with them.

In June 1946, some of these Japanese followers became instructors in a military school set up by the Viet Minh in Quang Ngai Province, Trà's birthplace, to teach fighting skills to more than 400 Vietnamese trainees.

In April 1975, Trà became Deputy Commander of the A75 headquarters under Senior General Văn Tiến Dũng during the Ho Chi Minh Campaign, the final assault on Saigon which led to the capitulation of the South Vietnamese government.

This account offended and embarrassed the leaders of the newly unified Socialist Republic of Vietnam and reportedly only one of the five volumes survived.
