Abstract. The needed information about the diversity data in the area that can be used in ecological areas in the future requested to be investigated. This study aims to analyze the diversity of macroalgae on the west coast of the coast of Pananjung, Pangandaran. The study was conducted from March to April 2020. This research used a survey method using three stations representing the research region. Sampling was taken out in the intertidal zone of the Coastal Coast of West Pananjung, Pangandaran Nature Reserve, West Java using the purposive sampling method. Data taken consisted of macroalgae types found at each observation station and measurements of environmental data consisting of pH, temperature, salinity, and flow velocity. The results showed that there were 21 species of macroalgae grouped into 9 orders, 13 families, and 3 divisions. The research can conclude that macroalgae in Pananjung Barat Beach Pangandaran have an index value that indicates a moderate category, an evenness index classified as a low category, and a dominance index classified as a low category that shows the dominant species was there and it was Padina australis.
