This study aims to explore the knowledge of the Portuguese community on child trafficking. Through an online inventory, with a sample of 492 community members, with a mean age of 40.53 and mostly female (70.7%), participants were more knowledgeable about forms of exploitation, risk and vulnerability factors, the profile of the victims, and the situation in Portugal about child trafficking. On the contrary, they were less knowledgeable about the dynamics of child trafficking. Having a college education, and contacting with the subject through informal or/and formal sources were predictors of a higher level of knowledge of child trafficking. This study reinforces the importance of the community as a whole in fighting child trafficking. To protect children against child trafficking, public policies should prioritize the role of the community. An empowered community can actively contribute to the prevention, signaling, and (re)integration of victims of child trafficking.
