Ocean Life 1: 55-60. Neogastropod is a taxonomic order of sea snails which have a well developed siphonal canal on their shell. The order includes many families and the highest diversity species can be found in tropical seas. Nguyahan Beach is a tropical beach located in Kanirogo, Sapto Sari, Gunungkidul, Yogyakarta, Indonesia. The beach is still natural and the substrates are dominated by fine sand and coral reef flats. The aim of this research was to understand the diversity of Neogastropod in the intertidal zone of Nguyahan Beach, Gunungkidul, Yogyakarta. The research was conducted on March - May 2017. The ecological parameters recorded were 27°C for water temperature, 3.4% for salinity, and 7 for pH. Sample collection was conducted using purposive sampling method. The result of this research shows 5 families of Neogastropod order, they were Muricidae, Nassaridae, Conidae, Columbellidae, and Mitridae, while the most diverse family was Muricidae with 3 genera.
