A total of 60 species of benthic macrofauna was collected by a grab sampler in the eelgrass bed in Kwangyang Bay, Korea. The dominant group was Polychaeta which was composed of 32 species. The dominant species were Platynereis bicanaliculata, Cirriformia tentaculata, Lumbrineris longifolia, and Cirratulus cirratus which accounted for approximately $63.7\%$ of the total numbers of benthic macrofauna. Seasonal variations in both species composition and abundance of the benthic macrofauna were major characteristics in the study area. Seasonal peak of number of species and abundance occurred in summer. And the lowest abundance occurred in winter. Seasonal dominant species were Platynereis bicanaliculata, Cirriformia tentaculata, Lumbrineris longifolia in spring and summer, and Cirratulus cirratus, Capitella capitata, Opisthobranchia in fall.
