The purpose of this study is to examine the relationship between global citizenship, multicultural personality and critical thinking in preservice teachers. The study group consisted of 363 preservice teachers who attend different departments of Faculty of Education in Kutahya. Data collection was done through Scale Universal Citizenship, Multicultural Personality Questionnaire and Critical Thinking Disposition Scale. Because the data exhibited a normal distribution because of preliminary analysis, Pearson product-moment correlation analysis of parametric tests and multiple regression analysis were used for data analysis. According to the findings, there is positive relationship between critical thinking and multicultural personality trends and global citizenship. In other words, as multicultural personality scores increased, level of global citizenship also increased. Or as critical thinking tendencies decreased, the level of universal citizenship decreased. In a society where people adopt universal values and can think critically, democracy, justice and tolerance become dominant. And in a globalized world where there is no critical thinking, consequences of wrong thinking and wrong decisions will end up with global violence, intolerance, injustice, and war that has high destructive power.
