Background <p>Community engagement represents a highly relevant way to integrate care across sectors and address social and structural determinants of health with populations. Yet, advancement of integrated care remains a challenge, particularly across health and social service organizations. Situating social cognition as a key element of integrated care, this paper explores the act community engagement within cross-sector integrated care.</p> Methods <p>An integrative review was conducted to determine what is known about the influence of community engagement on stakeholder perspectives in cross-sector integrated care, and to contribute to a more comprehensive evidence base for building and operationalizing equitable integrated care. In March 2022, four data bases were systematically searched, applying date limits 1990–2022, for English language articles that described community engagement in relation to integrated care and resulting stakeholder perspectives. Using matrices, numerous variables were extracted and synthesized using thematic analysis derived from the Rainbow Model of Integrated Care and a continuum of community engagement.</p> Results <p>In total, 13 studies were included in this analysis. Two studies included the hospital as a partner, and the rest were a mix of public, private health, and social service sectors. Positive stakeholder perspectives (<i>N</i> = 6) were found in studies that were consultative or collaborative, and led with social capital, shared reciprocity, and trust. Moderate and negative perspectives (<i>N</i> = 7) were found in studies that led with a utilitarian stance and lacked collective leadership, governance, longitudinal planning, and joint evaluations.</p> Conclusions <p>This review makes a singular contribution to cross-sector integrated care literature, utilizing perspectives from health and social service organizations to map what is known about the influence of community engagement on cross-sector integrative care. Perspectives from this review support calls for additional integrative care research exploring community-hospital relationships, and how power dynamics influence proximal and distal relationships, capabilities, motivations, and opportunities for collaboration.</p>
