The purpose of this paper is to examine the Greek millennial consumers‟ perceptions on the organic products that may affect their buying behaviour. The focus on this group principally derives from the millennials‟ importance for the contemporary firms. Issues that concern consumers‟ knowledge about organic products, consumers‟ views about organic products cost and, consumers‟ preferences for organic products and the main criteria that lead them to pay for the organic products have been examined. Data from questionnaires answered by Greek millennial consumers‟ have been statistically analysed. The cited literature data have contributed to the compilation of the research hypotheses, as well as to a better understanding of the research results. The results analysis has led to interesting results about the millennial consumers‟ perceptions on the organic products.
