Life satisfaction is an effective factor in establishing social order and harmony and realizing the progress and excellence of societies. Its lack will have consequences such as stress and anger at the micro level and weakening the spirit of altruism and cooperation at the macro level. This research aims to show what effect religion, which considers itself the way to human happiness, has on life satisfaction. The findings of this research, which were obtained by surveying a random sample of residents of Tehran aged eighteen and older, show that religiosity, as Durkheim said, has a significant positive effect on life satisfaction, and generally those who are more religious are more satisfied with their lives than others. Among the three dimensions of religiosity, religious rituals have a greater role in life satisfaction, but the effects of religious beliefs and religious behaviors are the equal.
