In the context of the long war in Ukraine and the challenges associated with the restoration of infrastructure, there is an urgent need to use social marketing as a tool for regional development. Social marketing promotes the active involvement of the public, public organisations, business and state institutions in the processes of reconstruction and ensuring regional sustainability. This allows not only to more efficiently coordinate the restoration of infrastructure, but also to support the development of human capital and social ties in the post-war period, which is critical for economic and social revival of the country. The purpose of the article was to study social marketing as an important tool for the development of infrastructure of regions of Ukraine under martial law, as well as to determine its key roles and opportunities in the process of reconstruction and recovery. To achieve this purpose, the following research methods have been used: analysis and synthesis for the study of scientific works, a scientific review method for generalising existing approaches, a comparative method for evaluating national and international practices, as well as a generalisation method for formulating conclusions about the role of social marketing in the conditions of infrastructure restoration. The paper examines the main guidelines for the implementation of social marketing in the process of restoring the infrastructure of regions of Ukraine under martial law. The tools for the implementation of specified guidelines have been analysed, and additional opportunities for the implementation of social projects have been also noted. The effects of using social marketing tools on the example of public campaigns, information platforms, social media and crowdfunding initiatives have been studied. Information on areas of infrastructure restoration, in which civil society participates on the basis of social marketing, including demining, reconstruction of critical infrastructure and residential facilities, has been systematised and summarised. The main projects and programmes contributing to the implementation of these areas have been determined
