The morphological diversity and proximate composition of pomegranate in Indonesia, particularly in Situbondo, East Java, had been relatively limited. This research aimed to characterize the morphology, assess diversity, and analyze the proximate composition of five accessions (white, pink, red, Indian red, and Australian red). The research was conducted at the pomegranate orchard (Baluran National Park Area) in Merak Halmet, Sumberwaru, Banyuputih District, Situbondo Regency, East Java, from September-November 2024. The method used purposive sampling based on criteria of trees bearing fruit annually and having complete plant parts, namely leaves, flowers, and fruits. Observation variables were plant height, growth habit, tree shape, leaf length and width, leaf blade shape, leaf tip shape, leaf color, calyx length and width, calyx and petal color, fruit length and width, fruit shape, fruit crown length, fruit color, sweetness level, aril length and width, aril color, seed length and width, and seed texture. Similarity analysis was performed using the NTSYSpc version 2.02i program with SimQual based on the Simple Matching coefficient, and cluster analysis using the Sequential Agglomerative Hierarchical Nested method Unweighted Pair Group Method with Arithmetic Mean to produce a dendrogram. The results showed that 30 pomegranate samples had morphological diversity in tree shape, leaf, leaf tip, fruit, leaf color, fruit color, aril, and sweetness level with a similarity value of 55%. The highest proximate contents were found in the red variety for water content (75.15%), in the pink variety for ash content (0.95%), protein (2.28%), and carbohydrate (27.15%), and in the Indian red variety for fat content (0.33%).
