Through a systematic literature review, we assess the current state of research on intrafamily conflicts in family firms, systematize the findings, and outline avenues for future research. Based on a review of 88 studies, we develop an input–process–output framework to synthesize input, process, output, and context variables and identify research gaps. The review contributes to the family business literature by bridging the family business and intragroup conflict literature, considering multiple levels of analysis (the individual, family, and firm), and presenting relevant research questions.
