The ineffectiveness of punitive approaches in controlling and reducing crime has drawn the attention of criminal policymakers in countries over the past four decades to the development and implementation of crime prevention programs.The United Nations, considering one of its duties, which is to combat crime, has considered crime prevention as one of the most important policies for responding to crime.United Nations Crime Prevention Guidelines, It has introduced 8 principles as the principles of preventive policymaking such as: knowledge Based Principle, Sustainability and Accountability Principle, Inclusion Principle,Interdependency and Differentiation Principle, Government leadership Principle, Synergy Societal Institutions Principle, Adjustment Principle, Localization Principle.In this research, which uses a descriptive-analytical method, while referring to library resources and collecting information through reading books, articles, theses, and analyzing laws, by comparing and examining the extent of compliance of the Crime Prevention Law approved in 2015 with the eight principles of preventive policymaking of the United Nations,We conclude that apparently, crime prevention policy in Iran has not been designed and implemented in a desirable manner and it seems that despite the provision of preventive duties sporadically in laws and regulations Crime Prevention Law as the most important pillar of preventive legislative criminal policy in Iran It mostly characterizes the organization and structure of crime prevention on a large scale in the country and the nature of the types of tasks, assignments, measures, and Public and private actions of Crime prevention has not drawn. Therefore, amending and revising the aforementioned law is recommended and emphasized.
