Lê Quang Vinh, popularly known as Ba Cụt, was a Vietnamese military commander of the Hòa Hảo religious sect, which operated from the Mekong Delta and controlled various parts of southern Vietnam during the 1940s and early 1950s.

Hòa Hảo is a Vietnamese new religious movement. It is described either as a syncretistic folk religion or as a sect of Buddhism. It was founded in 1939 by Huỳnh Phú Sổ (1920–1947), who is regarded as a saint by its devotees. It is one of the major religions of Vietnam with between one million and eight million adherents, mostly in the Mekong Delta.
