This article discusses the history of Vietnamese Americans and Vietnamese immigrants in Houston, Texas, and its environs. Vietnamese immigration has occurred in Greater Houston, including Fort Bend County and Harris County, since 1975, after the Vietnam War ended and refugees began coming to the United States. The earlier groups of refugees to Harris County, consisting of politicians, highly educated professionals, and military officers, arrived in the 1970s. Subsequent groups arriving in the 1980s and 1990s had less education and fewer resources than the earlier group of refugees.
