With an increasing population growth and subsequent physical expansion of cities and their tendency toward consumerism, waste generation and disposal of solid waste have increased and this non-normative and non-professional disposal has left deleterious effects of the environment. and far to reduce the quality of the urban environment has led. In Ardebil, the current location of waste disposal is in its north, i.e. the east side of Ardebil- Meshkinshar road. The present study is an attempt to analyze land suitability of the site with its current situation using a descriptive- analytical approach. It proposes an optimal location for the disposal of solid waste. Based on library studies and field observations, the parameters affecting the subject of the research were determined and the research criteria maps were produced using the Arcgis 10.2 software. All these effective parameters were evaluated and standardized using Fuzzy membership and Fuzzy overlay functions; therefore, all Layers were combined by taking advantage of fuzzy overlapping method. After overlapping the criteria maps in the software environment, the obtained results showed that locating the current landfill has not been in compliance with the standards. Hence, the optimal place to locate the landfill was proposed at 32 km southwest of Ardebil city
