Carettochelys insculpta (pig-nosed turtle) is one of protected species the Labi-Labi, which can be found only in southern Papua. Its distribution spread from the Merauke to Kaimana. Information of C. insculpta is very limited, such as its distribution and population status. Unfortunately, pressure and threats to C. insculpta are increasing inline with development in Papua. Information of distribution and population is very important for its future management. For those reasons, this study aims to determine the pattern of distribution and nesting habitat selection of C. insculpta in the Vriendschap river, Asmat regency, Papua. The study was conducted on 8 to 25 November 2011. The method used is survey with the transect system. Analysis of data on nesting habitat in Descriptive while the distribution pattern of nests made by the Ratio Variety Method and the Index Method. The results showed the distribution pattern of nests and tracks C. insculpta in Vriendschap River region iwas clumped with the parameters that most influence the presence of nest amount and tracks on the nest and laying sand is parameter of the vegetation cover area. Distribution of nests and tracks were found clustered in the Obokain region whose position is at the center of the length of the Vriendschap River.
