Therefore, this study aims to analyze the forms of Bajau ethnic beliefs in death rituals as well as a documentation effort. This research was conducted using qualitative methods, namely field research methods and focused interviews. The field study was conducted in Kampung Pangkalan, Kunak, Sabah. Meanwhile, a focused interview method was conducted on informants who were active and served as a community reference in the death ceremony such as Ustaz and Imam. Subsequently, secondary data were generated by taking past studies as reference sources as well as supporting this writing. In order to obtain authentic data, the thematic method and the concept of beliefs by Raymond Firth understanding were also done so that the data can be filtered according to appropriateness and accuracy. The findings found that certain beliefs in the death rituals of the Bajau community are closer and known to the elderly and old people only.
