Despite the importance of young people in determining future trends in women's advancement in the predominantly Muslim countries of the Middle East, no quantitative study to date has focused exclusively on the relationship between Islamic religiosity and gender egalitarianism among youth in the region. Using data from the Youth, Emotional Energy, and Political Violence Survey, I investigate the relationship between Islamic religiosity and gender egalitarianism among youth in Saudi Arabia and Egypt, devoting special attention to gender differences within countries. Particular dimensions of Islamic religiosity have different effects on gender egalitarianism by group, reflecting social currents in each country's civic sphere. For young men in both contexts, orthodoxy and mosque attendance are negatively associated with gender egalitarianism. In contrast, for Egyptian young women self-identified religiosity positively affects gender egalitarianism while for Saudi Arabian women, Islamic religiosity has no effect.
