ABSTRACT Aim To identify and synthesise qualitative and quantitative evidence of nurse managers' qualities, practices and styles related to leading nurses' interprofessional collaboration. Design Mixed‐methods systematic review. Methods Two authors independently selected studies based on predefined inclusion criteria, assessed quality and extracted data. A thematic synthesis with a convergent qualitative design was used. Data Sources CINAHL, PubMed and Scopus were searched from January 1, 2010, to September 7, 2025. Citations of relevant articles were screened. Results A total of 32 articles were included. The analysis revealed two leadership core qualities, five core practices, and three core styles of nurse managers that promote nurses' interprofessional collaboration. Core qualities were proficiency and mindset. Core practices comprised empowering, communicating and informing, commitment to interprofessional collaboration, creating possibilities, and establishing an enhancing atmosphere. Core styles included authentic, transformational, and transactional leadership styles. Conclusion The results reflect the situational nature of nursing leadership related to interprofessional collaboration. Successful leadership requires managers to adopt primarily a transformational leadership style, yet more traditional leadership is required occasionally. Results indicate that nursing leadership is foremost a process that evolves within its context. Implications for the Profession and/or Patient Care Greater clarity on how leadership influences nurses' interprofessional collaboration supports leaders, organisations, and educational institutions in developing and sustaining effective leadership. Impact This review demonstrates that the quality of nursing leadership is a central factor for successful interprofessional collaboration. Reporting Method The PRISMA guidelines for Systematic Reviews and Meta‐Analysis were used. Patient or Public Contribution This study did not include patient or public involvement in its design, conduct or reporting.
