Background Coastal regions in Southeast Asia are increasingly exposed to climate-related hazards. While a wide range of interventions has been implemented to address these risks, existing research remains fragmented across engineering, ecological, and social domains, with limited synthesis of how these approaches interact to support resilience. This review aimed to identify the types of coastal resilience interventions implemented in Southeast Asia, examine the resilience outcomes reported across multisystem domains, and identify remaining evidence gaps. Methods This systematic review examined English-language empirical journal articles on multisystem resilience interventions for climate-related hazards in Southeast Asian coastal regions. Non-empirical papers, grey literature, and studies unrelated to the geographical and thematic scope were excluded. Searches were conducted in Scopus, SpringerLink, and Google Scholar databases, last updated on 26 September 2025. Methodological quality was assessed using a checklist evaluating study rationality, rigor, credibility, and contribution. Following the PRISMA 2020 guidelines, 18 empirical studies were included in the review. Data were extracted and synthesized descriptively and thematically to map study characteristics, intervention types, resilience domains, outcomes, and remaining gaps. Results Three coastal resilience intervention domains were identified, consisting of Hard Engineering Solutions (HES), Nature-Based Solutions (NbS), Psychosocial And Community-Based (PS&CB) interventions. Concurrently, three multisystem configurations emerged: HES–NbS–PS&CB, NbS–PS&CB, and HES–PS&CB. Reported outcomes mainly focused on infrastructural and ecological resilience, while livelihood, governance, psychosocial, and well-being outcomes were less consistently assessed. Conclusions Coastal resilience in Southeast Asia increasingly combine engineering, ecological, and community-based strategies. However, psychosocial and well-being outcomes remain underreported, and evidence on long-term effectiveness is limited. Future studies should use more holistic and context-sensitive assessments that integrate social, livelihood, and psychosocial dimensions alongside engineering and ecological outcomes.
