In order to recognize the spatial planning system of the countries, we should first understand their planning and development system and then consider the experiences of those countries in the spatial planning system and its comparison with the current situation of the country of origin. The spatial planning system of Iran has not been successful in the field of urban development projects and has encountered failures. To eliminate these problems, using successful global experiences can be a suitable solution. Due to its leadership in the spatial planning system and successful performance in urban development programs and the use of active public participation, India has been investigated as a successful sample in this research. In this comparative comparison, two types of general knowledge (general, geographic, economic situation and intra-territorial divisions) and specific (macro planning system and spatial planning system) were obtained from two countries of Iran and India. The research method of the present study is qualitative and comparative and based on library and documentary studies. Based on the results, the approach and mechanism of spatial planning is more advanced in India and is shifting towards inclusive participation, but this movement is slow in Iran. In both countries, planning is done on various scales. The implementation and supervision system of India is based on a serious control and supervision system on land use and has strict rules in the field of development and construction regulations, but in Iran, the implementation of programs is average and supervision is not done well. In India, the planning process is first from top to bottom and then from bottom to top, but in Iran, the planning process is top to bottom. Finally, it can be said that India's planning and spatial planning system is more advanced compared to Iran in many cases, and those responsible for planning should consider the important points of India's plans and programs and how they are implemented.
