The article analyses the peculiarities of legal support of the European system of civil protection of population and territories. The author emphasizes that over the years, the EU has developed the main instruments through which all of its civilian security policy objectives are achieved.
 It is proved that building a modern and powerful civil defence system of the population and territories of Ukraine requires even more close cooperation with the relevant European structures, including within the framework of the European Union Civil Protection Mechanism (EU Civil Protection).
 The priorities of the EU's civil protection programs are to enhance cybersecurity and a safer online environment through the development and effective use of the digital capabilities of the European Union and its Member States. Significant attention is paid to supporting data and network protection, which strives for technological sovereignty while respecting privacy and other fundamental human rights. Joint European projects contribute to ensuring the security of services, processes and products, and ensure the formation of reliable digital infrastructures that can withstand and counter cyberattacks and hybrid threats.
 The study of the peculiarities of Ukraine's cooperation with the EU in the field of civil protection allows us to state that Ukraine's accession to the EU Civil Protection Mechanism will allow it to fully use all EU instruments and programs to develop the national civil protection system and attract assistance, and to continue future cooperation within the framework of the new strategic program of the EU Civil Protection Mechanism for 2024-2027.
 The peculiarities of using the experience of the EU countries to develop a system for ensuring public safety and protection of critical facilities during emergencies in Ukraine will be determined by the transformation of the public administration system in the post-war period.
