In the past time, up to 2000, the marine Amphipoda fauna of Vietnam was very few studied. Only some research works on the species composition and taxonomy of amphipoda gammaridea in coastal waters of Nha Trang Central Vietnam (Imbach, 1967: 4/ species), Bac Bo Gulf (Margulis, /968) and in brackish waters in Northern Vietnam (Dang Ngoc Thanh, 1968: 8 species). After the times, since 2000, marine research activities are largely developed in the whole marine waters of Vietnam. As an important component of benthic fauna, amphipoda group have been continuously explored in different areas of the Vietnam sea. By the research results on the species composition of amphopoda gammaridea, at present time about 18 fami/y, 42 genera and 105 species have been recorded. The most diverse in species composition familie.s are: Ampeliscidae (35 species), Melitide. (20 species), Talitridae (6 species), Lysianassidae (6 species), Urothoidae (5 species). Preliminary taxonomical analysis shows that fauna of gammaridea amphipoda of the Vietnam is rather characteristic, many new genera and species have been described: 20 genera and 47 species are newly recorded for the amphipoda fauna of the Vietnam sea 3 genera and 25 species are new to science. Some preliminary remarks on the taxonomical affinities with the amphipoda fauna of the adjacent waters are presented in the paper.
