Lâm Văn Phát was a Major general in the South Vietnamese Army of the Republic of Vietnam (ARVN). He is best known for leading two coup attempts against General Nguyễn Khánh in September 1964 and February 1965. Although both failed to result in his taking power, the latter caused enough instability that it forced Khánh to resign and go into exile.

Nguyễn Khánh was a South Vietnamese military officer and Army of the Republic of Vietnam general who served in various capacities as head of state and prime minister of South Vietnam while at the head of a military junta from January 1964 until February 1965. He was involved in or against many coup attempts, failed and successful, from 1960 until his defeat and exile from South Vietnam in 1965. Khánh lived out his later years with his family in exile in the United States. He died in 2013 in San Jose, California, at age 85.
