Considering the vital role benthic mollusks occupy in the marine food web and its significance in the world economy, this study was realized so as to give valuable information on the composition, diversity and abundance of benthic mollusks on the intertidal zones of Iligan City and Kauswagan, Lanao del Norte in Mindanao, Philippines. Samplings were done along the intertidal flats during low tide between the months of  June and July 2015 using the transect-quadrat methods. A total of 66 molluskan species were classified, with 56 species categorized as gastropods, while 10 species are bivalves.  Diversity profiles were calculated using Shannon-Weaver Index and results revealed diverse living assemblages of molluscan community in both study sites with several Nassarius species and Cerithium coralium being abundant. Comparing the abundance of mollusks among the 4 stations showed station 3 as having the lowest total number of individuals per m2. The result of the CANOCO indicated that total organic matter may have been responsible to such low abundance of molluskan assemblage in station 3. The current findings obtained from this study are of immense importance in understanding the reason behind the successful existence and dynamicity of intertidal communities in the coastal zones of Northern Mindanao as well as in the continuous monitoring and conservation efforts in these 2 areas considering that several industries are present along the coasts as well the existence of unregulated gleaning activities.
