**Abstract** **Objective:** The purpose of this scoping review is to examine what is known about the need for social support in the work environment during the return-to-work (RTW) process for injured workers, defined as those who have sustained a physical injury. A secondary goal is to examine the role of occupational therapists in facilitating social support to enable injured workers’ return to work as a productive occupation. **Introduction:** Social support is defined as direct or indirect care or help offered by co-workers or supervisors in the work environment. Research shows that social support from co-workers and can facilitate RTW.1 Research evidence indicates that workplace-based RTW interventions reduce disability duration, decrease costs, and improve worker outcomes.2 Occupational therapists are healthcare professionals whose scope of practice includes RTW and enabling social engagement. To date, no review has been conducted to map what is known about the need for social support in RTW, nor of the role of OT in enabling social support. **Methods: T**his scoping review will follow the JBI and PRISMA-ScR guidelines.
