This research was aimed to determine and study the abundance of benthic foraminifera on coral reef ecosystem and mangrove in the Coastal Waters of Lamreh, Aceh Besar. This research was conducted from April to May 2016 using purposive sampling method. Samples of foraminifera benthic were collected using a corer (paralon pipe). 229 individuals of foraminifera benthic belonging to 29 spesies was found. The most abundant species found in coral reef area was Spiroloculina sp. (339,70 ind/m2 or 14,17%) and Spriloculina hyalina (305,73 ind/m2 or 13,64%), while in mangrove area was Calcarina calcar with the abundance value of 356,69 ind/m2 or 20,59%. In this area the sediment was dominated by sandy sediment. Probably, It was due to the strong current and wave in the coastal waters of lamreh which inhibit the desposition of fine sediment
