A total of 24 species of atyid shrimps from the genera <i>Caridina</i> H. Milne Edwards, 1837, <i>Neocaridina</i> Kubo, 1938, <i>Atyopsis</i> Chace, 1983 have been recorded from Vietnam. With 22 species, the majority are from the genus <i>Caridina</i>. In 2013, Karge and Klotz mentioned the occurrence of four yet undescribed species belonging to <i>Paracaridina</i> Liang, Guo & Tang, 1999 in Vietnam without taxonomic details.In general, studies of freshwater atyids in Vietnam are limited and most Vietnamese taxa await a taxonomic revision. The available data do not fully reflect their estimated species diversity in the country and distribution data are deficient.
