The aim of this study is to analyse the complex interplay between religiosity, individual values, and support for human rights relevant to development, in a Romanian context marked by high levels of religiosity and low levels of socioeconomic development. The study employs a quantitative empirical research project involving high school students (N-681) in all the capital cities of the regional development areas of Romania. The results of hierarchical multiple regression analysis indicate that some dimensions of religiosity (religious belief and faith) are positive predictors of support for socioeconomic rights, universalism, and human dignity, and thus are conducive to sustainable development attitudes and practices. However, other dimensions, such as theism, positively predict traditionalism, while negatively predicting universalism, which may indicate a lower propensity towards supporting development. Hence, it can be inferred that for this sample, religiosity has a real but limited role in supporting some human rights and individual values conducive to a culture of development relevant to the United Nations (UN) 2030 Agenda. Individual values such as self-direction and universalism seem to play a more important role.
