Old Javanese literature is a significant part of Indonesia’s linguistic and cultural heritage; however, its continuity faces challenges from manuscript deterioration, limited access, declining engagement among younger generations, and evolving learning environments. This study examines the revitalization of Old Javanese literature in the digital era by focusing on preservation, adaptation, cultural transmission, and its implications for language teaching. Using a qualitative research design, the study combined documentary analysis, direct observation, and semi-structured interviews to gather complementary perspectives on the preservation and contemporary revitalization of Old Javanese literary materials. The findings indicate that revitalization requires an integrated approach that encompasses manuscript conservation and restoration, systematic digitization and database development, transliteration and translation, literary interpretation, and contemporary digital adaptation. Digitization is particularly important because it extends access to fragile manuscript collections while creating opportunities to transform literary heritage into educational resources. The study further demonstrates that Old Javanese literary genres and the mabebasan tradition have pedagogical potential for developing reading, vocabulary, speaking, interpretation, critical thinking, and collaborative meaning-making. Digital manuscripts, transliterations, translations, audio materials, annotations, and creative adaptations can therefore function as multimodal resources for contemporary language teaching. The study argues that revitalization should move beyond manuscript preservation toward a continuum of preservation, accessibility, learning, and cultural transmission. Integrating Old Javanese literature into language education can support heritage-based language learning while strengthening intergenerational cultural continuity in the digital era.
