The method used is a survey method. Determining the location and station of research was conducted by purposive sampling method. Sampling the species of the order Coeloptera was done by direct sampling, insect nets and traps insects. Samples were analyzed using species diversity index, relative abundance index, dominance index and evenness index. The results found were 437 individuals, 29 species and 12 families of the order Coleoptera. Family of the order Coleoptera cover, namely Carambycidae, Carabidae, Chrysomilidae, Ciidae, Coccinellidae, Curculionidae, Dystiscidae, Melandryidae, Phalacridae, Scarabidae, Staphylinidae, and Tenebrionidae. The family of Coccinellidae and Chrysomilidae have the highest number of species, namely 8 species. The highest number of individuals was found in the family Chrysomilidae of survey sites Station I, which is a species Lema diversa (114 individuals). Based on the survey area, the highest individual number of the order Coleoptera was found in the Station I (451 individuals). The species diversity of Coleoptera covers the riparian of the Mamberamo river in Papua different. Diversity index of insect order Coleoptera in four locations in Papua Mamberamo river riparian has been classified as moderate or not so diverse. Evenness index of the order Coleoptera in four survey sites of Papua Mamberamo river riparian lower appears quite evenly. Dominance index species of the order Coleoptera on the riparian of Mamberamo River in Papua showed the value <0.50, meaning do not happen dominance of certain species. The information of this research results is expected to be the initial information diversity and abundance of the order Coleoptera on the riparian of the Mamberamo river, Papua Province.
