The purpose of this study is to describe the morphological processes in Balinese adjectives. The data sources of this research are Balinese phrases and clauses uttered by selected informants and additional phrases and clauses made by researchers that informants have tested. The theory applied in this study is the theory of morphological processes by Bauer (2003). Methods and techniques of data collection were carried out by listening, probing, and introspection methods supported by tapping, recording, and speaking techniques. Methods and analysis techniques were carried out by the agih method, supported by the direct element technique and advanced technique. Formal and informal methods carried out methods and techniques for presenting the results of data analysis. The result of this research is the form of Balinese adjectives which can be divided based on the morphological process into monomorphemic adjectives and polymorphemic adjectives. Monomorphemic adjectives are found in Balinese, such as demen (happy), sweet, gede (big), and so on. Meanwhile, polymorphemic adjectives found in Balinese include (1) affixed adjectives; (2) reduplication adjectives without affixes; (3) reduplication adjectives with the prefix se-; (4) compounding of two free morphemes; (5) compounding antonyms; and (6) compounding of free morphemes and unique morphemes. There are also derivational forms with adjectives as the primary form, which include (1) adverbial form: reduplication adjective + se-/-né (2) imperative form: adjective
