Abstract: Many religious teachings encourage tolerance, but little is known about how religious trends, specifically the quest religious orientation, which is characterized by a lesser degree of dogmatism in dealing with religious beliefs and a greater belief in spiritual development as a journey that includes questioning and research, is related to tolerance, so the purpose of this study was to reveal the possible relationship between the quest religious orientation and tolerance, through the use of a sample of 300 male and female students at Salah al-Din University in Erbil, from the scientific and humanitarian specializations, where they completed the two scales of religious inquiring orientation (prepared by the researchers) and tolerance (prepared by the researchers). The results concluded that the research sample had an Quest religious orientation in addition to tolerance, while no statistically significant differences appeared according to the variables of sex and specialization for both variables, in addition to the existence of a statistically significant correlation between the religious orientation and tolerance in the research sample.
