Description Flood is becoming the most environmental challenge menacing Ado-Ekiti in recent times. The aim of this study is to evaluate and map flood risk in the study area, using GIS techniques, to achieve this aim, the study has the following objectives, assess the extent and magnitude of flooding in the study area, also it assesses elements at risk in the study area, hence integrate the outcome of these analysis in a GIS environment. Primary data was sourced with the use of structured questionnaires, while the secondary data sources are from Google earth map and literatures. Simple statistics was use to analyse the data to help develop indicators of vulnerability. A hazard and vulnerability maps were produced based on the perception the population living in the area, the map was then combined with the hazard map, and thus to produce an integrated risk map for the study area. Results reveal that from Vulnerability, Hazard and Risk maps showed that buildings closer to rivers and stream all have higher index. The impact of flood on households sampled revealed that some of the household believed that flood occurrence in the study area have some of impacts on their properties and expenditure. The methodology has proven to be a suitable tool to provide a first overview of spatial distribution of risk which is considered by the households
