Objective: This review will synthesize and integrate the best available evidence on the changes caused by the COVID-19 pandemic in access to and the provision of maternity services in Europe. The review will also consider health care professionals’ experiences in providing maternity care during the COVID-19 pandemic in Europe. Introduction: Governments and maternity services have introduced various protective sanitary and organizational measures to reduce the spread of COVID-19 and protect the global population, including health care professionals. Since March 2020, the number of publications on this topic has soared, yet little is known about the effect of the pandemic and the accompanying measures on access to and the provision of maternity care in Europe. Inclusion criteria: The review will consider quantitative, qualitative, and mixed methods studies on the impact of COVID-19 on European maternity services. For the quantitative component, the review will consider studies evaluating maternity services outcomes across all types of maternity care settings. For the qualitative component, the review will consider studies exploring maternity health care providers’ experiences and perceptions of the impact of the pandemic on care provided to women and their babies. Methods: Six bibliographic databases will be searched for published and unpublished studies since March 2020. Study selection, critical appraisal, data extraction, and data synthesis will follow JBI's segregated mixed methods approach. The quantitative component will be adapted to follow the JBI requirements for systematic reviews of etiology and risk. Systematic review registration number: PROSPERO CRD42021283878
