In recent years, rice crop intensification in Hau Giang province, which has put a lot of pressure and led to a great change in soil resources and its distribution. The previous soil map of the province (2008) has changed and out of date. Then The research aims: to identify the diagnostic horizons, properties, materials and to update the soil map. The field data was collected as soils profile description from 175 profiles, and 51 profiles for soil analysis. Soil classification was followed WRB 2006. The results shown that two major soil groups were found, in which four diagnostic horizons (Mollic, Umbric, Plinthic, and Sulfuric); one diagnostic property (Gleyic); and one diagnostic material (Sulfidic) were identified, and 15 soil types were classified. The Gleysols soil group have 14 soil types (hamoGL, hamoGL(hu), monplGL), (moGL(ptip), moGL(ntip), moGL(dtip), (umGL(ptio), huGL(ptio), umpplGL(ntio), umGL(ntio), huGL(ntio), umGL(dtio), (mowsGL(ntip), umwsGL(ntio)) total area of 9,551.32 ha, accounting for 59.34%; while Anthrosols soil group have one soil type (RGah) area of 66.252,91 ha, accounting for 40.66%. Soil name and soil map of Haugiang was updated according to WRB 2006 and can be used for further study and land use plan of province. Rice cultivation is dominated on most of Gleysols soil groups, while pineapple, sugarcane and fruit crops grow on the raised bed are mainly on Anthrosol soil group, where acid sulfate soil is dominated
