The information on the state of knowledge about the findings and status of the raccoon in the fauna of Ukraine and the neighboring countries is presented, with a detailed analysis of the findings in Polesia, in particular the first case of free state of raccoon in winter in the residential area of the Kyiv metropolis is described. The analysis of available sources shows the widespread practice of keeping raccoons in private zoos and as pets, and also the emersion of regular reports of escapes the individuals from captivity. Examples of wild state are given, that is, raccoons are able to survive without human concern, as well as to find food and shelter on their own. Kyiv's findings testify the rapid synanthropization of the species, in contrast to the exanthropic settlements of the neighboring regions of Belarus, which have ceased to exist at this point in time. All this is considered as evidence of the first stages of formation of a syntanthropic population of the species with the prospect of further formation of a free population. Comparison of the data obtained with current surveys on alien species in Europe reveals the coincidence of such findings and the fact that they are a natural continuation of the invasion of the species in Europe with the further expansion of the limits of free population spread to the east. All this is thanks to escapes from contact zoos and other places where the species is held in captivity, as well as the active adaptation to new living conditions due to climate warming and increasing the probability of survival of the species in natural conditions. The main habitat of the species under current conditions is not natural, but synanthropic locations, in particular residential areas of cities, but the prospect of exanthropization is quite real.
