This study assessed flood vulnerability in Egor local government area of Edo state by using Analytical Hierarchy Process (AHP) . Seven indicatorselevation, slope, drainage density, soil type, distance from streams, rainfall and land use and land cover were considered and their weight of importance were determined from pairwise comparison matrices and expert judgment. Multiple sources of secondary data like 30M resolution Landsat 9 satellite data derived from United States Geological Services, Tropical Rainfall Measuring Mission as well as other primary data gotten from response of questionnaire administered. The resulting map was classified into five levels of flood vulnerability and the communities were characterized according to their level of vulnerability. Findings showed that the villages Ogunwenyi, Obanyotor, Ogboyoko, Useh and Oghoghugbo were all classified under areas highly vulnerable to flooding. Findings provide baseline data for targeted flood mitigation, urban planning and early warning systems in Egor LGA
