Benthic foraminifera are one of the most highly distributed and abundance microfauna in the oceanic habitat, from the deep-sea to the shallow intertidal environments. This study investigates the distribution of benthic foraminifera on selected marine sediments taken from Pahang River estuary with the coordinate between latitude 03°42.575’ to 3° 25.545’ N and longitude 103°25.670’ to 103°41.903’, respectively. Twenty surface sediments samples were collected for grain-size analysis and foraminifera assemblages. The sediment samples collected were mostly sand with total of 13, 173 specimens of foraminifera were collected representing 63 species from 22 families. SEM images taken by Hitachi Tabletop Microscope (TM-1000) were used to assist the identification procedure. Amphisteginidae is the most dominant family, with percentage of 50.6% and the dominant species is Amphistegina lessonii, 35.4%. The highest abundance of foraminifera was recorded at station 7 (1,140 individuals) while the lowest was at station 1 (180 individuals).
