Little Saigon is the preferred name of Vietnamese refugee communities throughout the world. This article focuses primarily on the largest such community, in Orange County, California. This suburban ethnic enclave is home to the largest concentration of overseas Vietnamese, nearly 200,000, or 10 percent of the Vietnamese American population. Because of its size, location, and demographics, Little Saigon is also home to some of the most influential intellectuals, entertainers, businesspeople, and politicians in the Vietnamese diaspora, many of whom are invested in constructing Little Saigon as a transnational oppositional party to the government of Vietnam. Unlike traditional immigrant ethnic enclaves, Little Saigon is a refugee community whose formation and development emerged in large part from America’s efforts to atone for its epic defeat in Vietnam by at least sparing some of its wartime allies a life under communism. Much of Little Saigon’s cultural politics revolve around this narrative of rescue, although the number guilt-ridden Americans grows smaller and more conservative, while the loyalists of the pre-1975 Saigon regime struggle to instill in the younger generation of Vietnamese an appreciation of their refugee roots.
