Cyber-violence has existed for more than 15 years, but there too little attention has been paid to it and too little action in dealing with it. The main aim of this paper is to discuss and analyze the problem of migrant children and cyber– violence. We draw particular attention to hate speech. Which has already been noted as a threat in Italy as well as Poland. The aim of this research is also to put forward some suggestions which could be useful in further researching of migrant children and hate speech. This paper contains the first results of our research. This study is based on reports, academic literature, interviews and case studies. We address the problem of migrants’ children as we consider it to be a significant element of public discourse. Unfortunately it has not been subject of significant debate in the public domain to date, either in Italy or Poland.
