Purpose Online grocery service (OGS) has significantly grown in recent years, particularly during the Covid-19 pandemic. This surge has attracted significant scholarly attention and resulted in many scientific articles in the last five years. Adopting a bibliometric review approach, this study attempts to comprehensively and systematically analyse the academic literature on OGS. Design/methodology/approach A Scopus search using pertinent keywords followed by PRISMA screening identified 384 relevant articles. Articles were analysed using VOSviewer and Biblioshiny, which employed citation and thematic analysis. Findings The study identifies the significantly impactful authors, articles, and journals. While the analysis reveals the evolution across four time-frames, it also highlights the clusters representing the literature strands. Six major themes are identified in the literature, and potential future research enquiries are suggested. Originality/value As the first study to include over 350 articles, it comprehensively represents the current state of the OGS literature, utilising performance and thematic analysis techniques. The article contributes significantly to the academic discourse surrounding OGS by synthesising and presenting diverse themes. Further, the future research questions provide a foundation for advancing the literature and guiding future scholarly work in the OGS domain.
