This study aims to describe the cultural elements in the novel Negarabatin: Negeri di Balik Bukit by Udo Z. Karzi and their implications for teaching the Lampung language in schools. Using a qualitative descriptive approach, data were collected through reading and note-taking techniques, then analyzed using content analysis. The results show that six of the seven cultural elements of Lampung are depicted in the novel. Language is reflected in the use of traditional words such as memmang, ugu tegolan, and greetings like pakngah and paklunik. Knowledge elements are evident in traditional healing practices using jerangau and jahhik, as well as the preparation of traditional foods like kekalik. Social organization is seen in the system of greetings and decision-making within families. Tools and technology are depicted through bamboo ladders, stoves, and petromax lamps. Livelihoods are represented through farming activities, nayuh, and belangok, while religion is reflected in rituals such as ngakan menyan and ngebebali. These findings can serve as teaching materials for Lampung language classes in Grade 10 Phase E, particularly the reading and viewing elements of the Merdeka Curriculum.   Penelitian ini bertujuan mendeskripsikan unsur-unsur budaya dalam Novel Negarabatin: Negeri di Balik Bukit karya Udo Z.
