The relevance of the research on the resilient potential of public organizations in Ukraine is determined by the need to increase the regenerative capabilities of territorial communities within a limited time frame and with restricted resource suport. The purpose of the article is substantiating the resilient potential of public organizations as an effective tool for increasing the adaptive capacity and self-organization of public community, mitigating the destructive consequences and accelerating recovery of territorial communities during the Russo-Ukrainian war and in post-war period. The novelty of the article consists in identifying the impact of public organizations on the resilient recovery of territorial communities in the conditions of the Russo-Ukrainian war. The research was carried out using the systems approach method, techniques of abstraction and generalization, functional and comparative analysis, statistical methods and data analysis, graphic method. The influence of public organizations on the resilience of territorial communities was analyzed by means of correlation-regression analysis. Three indicators of the resilient potential of territorial communities of the country were selected according to the criterion of significance and the existence of a cause-and-effect relationship. Namely: profitability of local budgets per person, cash income of households, the size of informally employed population as a sign of the shadow economy. The main functions of public organizations in ensuring the resilience of territorial communities have been disclosed. It is substantiated that the most effective tools for the influence of public organizations on ensuring the resilience of communities in the conditions of the war and post-war period are active means (promotion of citizens’ mobility, formation of public opinion, public control) and segmental tools (influence on certain population groups, infrastructure objects, territories etc.) with a fixed effect (legal assistance to internally displaced persons, reconstruction of the destroyed property and healthcare facilities, improvement of epidemic living conditions, ensuring the operation of a humanitarian center, collection of necessary information).
