The article is devoted to reviewing the government’s response of Southern European countries (Italy, Spain, Portugal and Greece) to the full-scale invasion of Russia in Ukraine on 24 February 2022, which is based on the analysis of the researches, analytical papers, and official reports of the state authorities and mass media. Coverage of this topic is explained by the necessity of the full exploration of the Sothern European governments’ key approaches in supporting Ukraine in the struggle with the Russian army, as well as, discovering some new perspectives, using the comparative and transnational methodology. It is defined the term “Southern Europe”, and also outlined the main historiographical interpretations of the countries of the region. Preference is given to a pragmatic approach for characterising the countries of Southern Europe. The central studies of Ukrainian-Italian, Ukrainian-Spanish, Ukrainian-Portuguese and Ukrainian-Greek relations, official reports and mass media used in the study are analysed. It also analyses and compares the changing Southern European governments’ attitudes towards their supporting Ukraine after the Revolution of Dignity, the illegal annexation of Crimea, and the beginning of war in Donbas in 2014, with the united international response after the full-scale Russian invasion on 24 February 2022. In general, the governments of Italy, Spain, Portugal and Greece changed completely their policy of supporting or non-supporting Ukraine in the war. If after 2014 they tried to be pragmatic in the question of cutting ties with the Russian Federation in their foreign policy activity, then after the full-scale invasion in 2022 they strongly condemned Putin’s regime and agreed to provide assistance to Ukraine to the extent of their military and financial capabilities. The study found that the assistance of Southern European countries has been provided on the Atlantic (through NATO) and European (through EU) levels, as well as national. Defence ministers of the governments of Southern Europe are among the members of the “Ramstein” meetings, where the provision of military aid to Ukraine is coordinated. The countries of the region have so far given priority to humanitarian, financial aid and lethal weapons assistance (but not heavy ones), and have also accepted a large number of Ukrainian refugees. The assistance provided at each of the levels is illustrated by specific examples. Otherwise, Russian influence on domestic policy, national populistic parties and single members of the government or parliament is still strong. For instance, the Italian governmental crisis that happened in the mid-summer was the result of the unpopular and strong position of the prime minister Mario Draghi in his unwavering support of Ukraine. The countries of the region also see the Russian-Ukrainian war as an opportunity for them to strengthen their influence in the Mediterranean.
