This Study Investigates the relationship between strategic leadership styles and organizational performance in a cross-national context, with a focus on Indian and multinational corporations operating across diverse industry sectors. Drawing upon a mixed-methods research design encompassing survey data from 412 senior managers across 38 organizations and qualitative insights from 24 in-depth interviews, the research examines how transformational, transactional, and servant leadership paradigms influence financial performance, innovation capacity, employee engagement, and sustainability outcomes. The findings reveal that transformational leadership demonstrates the strongest positive correlation with long-term organizational performance (r = 0.71, p < 0.01), while servant leadership significantly predicts employee retention and organizational citizenship behaviour. Transactional leadership, though associated with short-term efficiency gains, shows diminishing returns in volatile market environments. Moderation analysis indicates that organizational culture and institutional context play critical roles in amplifying or attenuating leadership effectiveness. The study contributes to strategic management theory by extending the Upper Echelons perspective and offers evidence-based implications for leadership development, corporate governance, and human capital strategy in emerging and developed economies
