English as a foreign language (EFL) education has become increasingly ubiquitous in Eastern Asian early childhood education (ECE) settings, but the studies on this phenomenon have not been thoroughly reviewed. This scoping review investigates the scope and findings of the current literature regarding this under-researched phenomenon. Through a five-step protocol, 17 empirical studies published during 2012–2022 are included. Findings indicate that: (1) there are four major research areas: education policy, education technology, teacher and teacher education, and curriculum and pedagogy; (2) Hong Kong receives the most research attention; (3) teachers’ knowledge and beliefs, implementing early EFL education, and effects of interventions constitute three prominent research themes. This review also identified research gaps and highlighted the need for more quantitative research on early EFL education in other parts of Asia, the planning and implementation of EFL policies in micro-level contexts, and in-service educators’ beliefs and practises.
