Background: Multicultural counseling plays a vital role in guidance and counseling, particularly in Indonesia, which is characterized by extensive cultural, ethnic, religious, and linguistic diversity. Objective: This study aims to examine the roles of counsellor ethics and multicultural competence in the implementation of multicultural counseling and to identify the challenges encountered in practice. Method: The study employs a qualitative literature review design, analyzing relevant academic journals, books, and scientific publications on counsellor ethics, counsellor competence, and multicultural counseling. Result: The findings indicate that professional ethics serve as a fundamental guideline for counsellors in respecting clients’ rights, dignity, and cultural values, while multicultural competence enables counsellors to understand cultural differences, manage personal biases, and apply appropriate counseling strategies. The integration of ethical principles and multicultural competence contributes significantly to the delivery of inclusive, effective, and equitable counseling services. Conclusion: The study emphasizes that strengthening ethical awareness and multicultural competence is essential for enhancing the quality and professionalism of counseling services in multicultural contexts. Originality/Value: This review article comprehensively consolidates professional ethics and counselor competency paradigms in the field of counselor education and multicultural counseling by synthesizing literature on the dynamic interdependence between professional ethical standards and multicultural competence in managing personal biases and navigating diverse sociocultural client identities, an area that has remained underexamined through an integrated lens. This review maps existing theoretical and methodological gaps while serving as a strategic benchmark, contributing to the development of a robust conceptual framework for culturally responsive counseling practices, the enhancement of professional counselor training curricula grounded in pluralistic ethics, and the orientation of future empirical research agendas regarding cross cultural counseling efficacy in pluralistic societies.
