Ho Chi Minh City (Vietnamese: Thành Phố Hồ Chí Minh), commonly known as Saigon (Vietnamese: Sài Gòn) or by the abbreviations HCMC or HCM, is the largest city in Vietnam and the former capital of the Republic of Vietnam (South Vietnam). Following the fall of Saigon in 1975, Saigon was "officially" renamed Ho Chi Minh City. However the old Saigon name is still used by both Vietnamese and foreigners, especially when referring to the most central part of the city to which most tourists flock. (Ho Chi Minh City Wikitravel)
