The paper aims to investigate the evolution of the theme knowledge sharing in business education in the academic literature. Based on an extensive search, it can be stated that this is the first systematic review of this topic. The method employed in this study was a systematic review that covered publications from 1997, when the first paper relating the topic was published in the selected databases, to 2020. The analysis was based on 306 articles. From them, 251 articles came from Scopus and 108 from ISI Web of Science. Some articles are in both databases. Four periods were identified: embryonic, emergent, growth young, and growth highest. One of the findings is that knowledge sharing in business education is growing in virtual environments, especially in the last year, where the COVID 19 pandemic restricted the option of face-to-face education in classrooms. It is recommended that business schools decrease the percentage of time they spend in lectures and increase the time and strategies in which students share knowledge, discuss problems and make decisions based on collective reflection. © The Authors, 2021.
