The worldwide growth of construction megaprojects has triggered an increasing number of academic publications in the past few decades. Therefore, this paper aims to systematically review studies on the critical success factors (CSFs) to identify the CSFs for construction megaprojects from academic journals between 2000 and 2018. The research results indicated an increasing research interest in the investigation of critical factors for CMS since 2000. Meanwhile, based on the number of 27 journal articles, a total of 33 CSFs were identified eventually and the top five were adequate resource availability, partnering/relationships with key stakeholders, adequate communication and coordination among related parties, public support or acceptance, and clear strategic vision. A checklist of CSFs for CMS was developed and could render new insight for researchers and practitioners to conduct further studies and enhance megaproject management in practice. Moreover, the results would also enrich the theory of megaproject management.
