This article explains, in a narrative-analytical manner, the Pendalungan culture in the Eastern Salient of Java. The Eastern Salient of Java is located in the far eastern part of East Java, known as 'Pendalungan'. This article departs from the history of Pendalungan, whose cultural identity is unclear. Therefore, this article will briefly explain the migration of ethnic Javanese-Madurese to East Java, the interpretation of Pendalungan, and the results of the analysis of the cultural trajectory of Pendalungan in the Eastern Salient of Java. In writing this article, researchers combined historical methods with cultural approaches and accumulated theoretical concepts. The main finding in this research is that the Pendalungan culture is one of the keys to building the local identity of a particular area, in this case, the Eastern Salient of Java. The Pendalungan culture, due to the ethnic acculturation version of the Eastern Salient of Java Region, is not located in a theological doctrine theory. The cultural and religious dimensions of the Eastern Salient of Java Pendalungan culture lie precisely in the aspects of identity and the formality of forms that develop and shape the face of culture following the direction of purpose and substance in each particular regional locality. None other than these developments are aligned with the cultural and religious realities of the people in the Eastern Salient of the Java Region. It is the foundation that paved the way for the development of the Pendalungan culture in the Eastern Salient of Java until today.
