We examined estuarine macrobenthos in Namdaecheon estuary, Gangneung, Korea, September 22, 1997. A total of 56 species were found together with an abundance of 378 individuals $m^{-2}$/ and a biomass of 20.79 gWWt $m^{-2}$. The major dominant species were unidentified oligochaete followed by different species of polychaetes Hediste japonica, Rhynchospio glutaea, Poecilochaetus trilobatus, Scoloplos armiger, Spiophanes bombyx and a talitrid amphipod Platorchestia crassicornis. The study area was divided into two different groups of stations and species, based on the q -mode and r-mode clustering analysis. In case of q-mode, there are two groups: one is a marine station group and the other is estuarine group. The r-mode clustering analysis showed the two main communities as follows; 1) Marine species group occurred only at station 7, 8 and 9 and 2) Estuarine species group composed of the species present at station 1 to 6 and 10 to 15. In the number of species, the estuarine station group includes 13 species, whereas 43 species were presented in the marine station group. Total macrofaunal abundance and total biomass were higher in the marine station group than those in the estuarine group. The species diversity index was also high in the marine group (> 2), whereas it was less than ca. 1 in the estuarine group.
