Piil Pesenggiri is a philosophy of life of the Lampung people that represents a system of values, social ethics, and cultural identity passed down across generations. However, the process of modernization and the flow of globalization have driven a shift in values that has weakened the younger generation's understanding of the substantive meaning of Piil Pesenggiri. This study aims to examine the role of Piil Pesenggiri values in strengthening the cultural resilience of the Lampung people and identifying relevant revitalization strategies in the context of modern culture. The research method uses a descriptive qualitative approach through a literature review of classical manuscripts and ethnographic studies, including the works of Hadikusuma (1977/1978) and Sayuti (1985). The results show that the four main values of Piil Pesenggiri nemui nyimah, nengah nyappur, sakai sambayan, and juluk adok function as pillars of social morality that maintain harmony, self-esteem, and community solidarity. Revitalization of these values can be done through culture-based education, strengthening traditional activities, and integration in the local content curriculum so that Lampung's local wisdom remains alive, adaptive, and relevant in facing the dynamics of social change..
