Reproducibility is a critical component of research integrity, enhancing the quality, efficiency, and trustworthiness of scientific knowledge. Despite increasing attention, reproducibility remains insufficiently prioritised within the scientific agenda. Research funders are uniquely positioned to drive a culture change by shaping expectations and requirements for research organisations and research they fund. To support funders with this role, we co-created the Reproducibility Promotion Plan for Funders (RPP) in collaboration with a community of international funders. The RPP provides a structured a set of recommendations to support funders in promoting reproducible research practices across three themes: (1) Policy and Definitions, (2) Evaluation and Monitoring, and (3) Incentives. We offer practical recommendations, that can be tailored to fit funders’ individual needs, and best practice examples to further strengthen its usability.
