In this paper, we examine the relationship between religiosity and altruistic value orientation in economically developed European societies. The data come from the European Social Survey (ESS). Religiosity within ESS is measured by three dimensions – self-evaluation, frequency of attendance of religious services apart from special occasions and frequency of praying apart from at religious services. Altruistic value orientation is measured by rating of personal importance of helping people and caring for others well-being. Using cross-sectional data from the last round of the ESS (from 2016), from thirteen economically developed European countries, we revealed very weak relationship between all three dimensions of religiosity and altruistic orientation. Secondly, using data from all the prior rounds of the ESS, from 2002 to 2016, we also examined trends of both religiosity and altruistic value orientation within the same societies. The results indicate decline of religiosity and rise of altruistic orientation in all of examined countries.
