<p>Urban planning research is inherently complex, requiring diverse methodological approaches to effectively capture the multifaceted nature of urban issues. Traditional reliance on single-method approaches often limits the depth, reliability, and applicability of findings. This study advocates for methodological triangulation as a critical strategy for enhancing urban planning research. By integrating qualitative, quantitative, and mixed-method approaches—such as surveys, literature reviews, systematic reviews, case studies, and bibliometric analyses—researchers can produce more comprehensive, nuanced, and reliable insights. Methodological triangulation strengthens research validity, bridges theoretical and practical knowledge, captures spatial and temporal dynamics, and accommodates multi-stakeholder perspectives in urban planning. Despite its advantages, challenges such as epistemological incompatibilities, resource intensiveness, and difficulties in synthesizing diverse findings must be carefully managed. This study outlines a structured approach to implementing methodological triangulation in urban planning research, providing a framework for researchers to enhance the rigor and relevance of their work. By adopting triangulation, urban planning research can generate more robust, evidencebased solutions that inform policy and contribute to the development of sustainable, resilient, and inclusive cities.</p>
