<p>This study examines the process of fostering empathy in preschool children through the use of migrant Persona Dolls. The research was conducted using a convergent mixed-methods design. The quantitative dimension employed a pre-test–post-test quasi-experimental design without a control group, while the qualitative dimension utilized a phenomenological approach. Quantitative data were collected using the Empathy Scale for Children (ESC), whereas qualitative data were obtained through semi-structured interviews with children. A total of 39 children aged 5 and 6 participated in the study. The quantitative findings indicate a significant increase in children’s empathy levels following the intervention (<i>p</i> &lt; 0.05). When the retention of the intervention was tested, a decline in empathy levels was observed after the intervention. Qualitative findings suggest that, compared to the pre-intervention phase, children demonstrated an increased willingness to play with their migrant peers, showed improvements in understanding the emotions of migrant children, and exhibited a reduction in unfriendly feelings toward them. Additionally, unwanted attitudes were found to be associated with family influences. In conclusion, the Persona Dolls approach supported the development of empathy skills and enhanced anti-bias education.</p>
