This study aimed to examine the relationship between Spiritual Leadership and the dimensions of Organizational Citizenship Behaviors (OCB) of school principals from the perspectives of primary school teachers. A quantitative survey was performed on a sample of teachers (N = 383) from primary schools to study the influence of spiritual leadership on OCB. The spiritual leadership as an independent variable and organizational citizenship behavior subscales (Altruism, Conscientiousness, Sportsmanship, Courtesy and Civic Virtue) were checked for their inter-correlations. Pearson's Product Moment Correlation and Multiple Linear Regression Analysis techniques were used for the analyses. All the variables are observed to significantly correlate with each other, and it is seen that spiritual leadership predicts all four dimensions of OCB, especially civic virtue. It is understood that spiritual leadership may strongly contribute in forming more solid ground for OCB to pervade in an organization.
