Objectives <p>This review examined the effectiveness of mindfulness-based interventions (MBIs) in enhancing mother–infant attachment, defined as the child’s bond with a caregiver offering a secure base for exploring the world.</p> Method <p>Following PRISMA guidelines, a search was conducted in PubMed, PsycINFO, ScienceDirect, Cochrane Library, PsycArticles, ProQuest, Google Scholar, ERIC, Semantic Scholar, SAGE, Scopus, and Taylor &amp; Francis Online, with no date restrictions. English studies assessing mother–fetus or mother–infant bonding after mindfulness interventions were included. Data came from India, Indonesia, Iran, Korea, Turkey, and the USA.</p> Results <p>Out of 597 records initially retrieved, 17 studies met the inclusion criteria including: eight randomized controlled trials (RCTs), one cross-sectional study, three quasi-experimental studies, one exploratory clinical outcomes study, two longitudinal studies, one pilot feasibility study, and one feasibility study. Fifteen studies reported significant improvements in attachment following an MBI. Fifteen studies assessed prenatal attachment; 13 showed positive results, including six RCTs. Three studies examined postnatal attachment, but only two reported benefits, although these results should be interpreted with caution. MBIs were associated with increased mindfulness and significant reductions in anxiety and depression among pregnant women. Improvements in sleep and stress were also observed, though not explored in depth in this review.</p> Conclusions <p>Overall, the review highlights promising benefits of MBIs for maternal–fetal attachment and offers directions for future research. These findings support integrating MBIs into prenatal care to enhance maternal mental health and mother–infant bond.</p> Preregistration <p>The study was registered on PROSPERO under the identification number CRD42024528627.</p>
