Despite growing interest among researchers and practitioners in the topic of work passion, multiple conceptualizations of this construct exist, and research within each conceptualization has advanced along independent streams with little integration or cross‐fertilization. In this editorial, we provide a brief overview of the literature on work passion (including employee passion and entrepreneurial passion), describe five extant conceptualizations, and present criticisms and opportunities for future research. We discuss the six papers in this special issue on work passion research and strongly encourage additional research that tames breadth and promotes depth in the study of passion at work.
