The aid for the Ukrainian refugees in Poland has been analyzed almost since the beginning of the full-scale Russian aggression against Ukraine in February 2022. In 2023, the first comprehensive studies on that topic were published. This article aims to map the state of research on Polish assistance – both direct and indirect support – to the Ukrainians fleeing the war to determine which issues have been the subject of analysis and which have been ignored. On the basis of the publications indexed in Scopus and in Google Scholar, a total of 110 publications dealing directly with the topic of the Polish aid for the Ukrainian refugees were identified. They include working papers, articles and books which were published from March 2022 to November 2023. The article is divided into four parts. The first part has an introductory character and aims at presenting the publications, which explain why Poland and its inhabitants massively helped the Ukrainian refugees. The next three parts focus on the role of the main types of actors involved in assisting the Ukrainians in Poland, i.e. state-institutions, actors such as non-governmental organizations, business, educational institutions and churches, and finally Polish society.
