Passion is a fundamental driver of social and economic behavior and plays a salient role in entrepreneurship. However, the literature at the intersection of passion and entrepreneurship faces two critical challenges that are hindering progress. First, most studies draw on a narrow definition of passion, focusing on passion for specific entrepreneurial activities, potentially overlooking other important passion types that shape the entrepreneurial experience and outcomes. Second, studies (either explicitly or implicitly) assume and measure passion as a static (i.e., time-invariant) concept, not accounting for how passion may evolve over time and along the entrepreneurial journey. Through an integrative review of 220 academic articles across management and social sciences, we 1) introduce a novel typology of passion in entrepreneurship that captures its conceptual and operational heterogeneity; 2) propose a dynamic (i.e., time-variant) perspective on passion in entrepreneurship to explain how passion functions over time and across levels; and 3) offer a research agenda for advancing theory and methodology in this domain.
