This research explores the relationship between transformational and transactional leadership styles and their effects on employee productivity within municipalities in Eastern Gilan Province. The study adopts a quantitative, descriptive-survey approach with a sample size of 384 respondents determined by Morgan’s formula. Data was collected through a structured questionnaire using a 5-point Likert scale. Multiple linear regression analysis, conducted via SPSS, demonstrates that transformational leadership has a more significant positive impact on employee productivity compared to transactional leadership. The study also verifies essential regression assumptions, including linearity, normality, homoscedasticity, and multicollinearity. Descriptive statistics reveal key demographic insights, contributing to a deeper understanding of the participant pool. The findings suggest that municipalities should emphasize transformational leadership practices to foster higher employee productivity. The research concludes with practical recommendations for enhancing leadership approaches in public institutions.
