Ngawi Regency Regional Regulation Number 10 of 2011 concerning the Ngawi Regency Spatial Planning Plan for 2010-2030, Article 23 paragraph 2, Ngrambe District is included in the landslide-prone area and is classified as the most landslide-prone area because it has a geographical location close to bare and critical forests besides its location on the slopes of Mount Lawu. The method used in this study is quantitative with data collection techniques used in the study, namely Observation and Related Agencies. The purpose of the study was to determine the level of landslide-proneness using the Weighted Overlay Landslide Method in Ngrambe District. The results of the analysis based on the calculation of the spatial analysis, it is known that the results of the Weighted Overlay analysis in the landslide-prone area in Ngrambe District show the results of landslide vulnerability, namely low with an area of 3401.16 Ha, medium with an area of 1676.69 Ha, high with an area of 405.43 Ha, and very high with an area of 1410.61 Ha.
