There appears to be a lack of existing data that comprehensively summarizes the evidence of children and adolescents’ active travel in the Republic of Ireland. In lieu of this, a scoping review was conducted to map the existing literature (2000–2020) on children and adolescents’ active travel in the Republic of Ireland. A scoping review design extracted a total of 19 publications, which show a consistent focus on the identified population’s active travel patterns, mainly to and from school, mostly self-report and cross-sectional research study designs; however, there are few longitudinal data, intervention and participatory studies. Key issues from these identified scoping review studies are discussed with the potential to better inform policy makers, practitioners and researchers to delineate programmes and strategies for promoting active travel among children and adolescents in the Republic of Ireland.
