Abstract: This study aims to examine the role of leadership quality on the relationship between market orientation and the performance of organization. Data collection was conducted with the help of mail questionnaire survey coupled with a simple random sampling method in choosing organizations comprising the sample study. The study sample consisted of one hundred and fifty eight Malaysian manufacturing firms. According to the study’s results, leadership quality partially moderated the market orientation-performance of organization relationship. Despite the lack of evidence on the impact of leadership quality on the relationship between market orientation and performance of organization, individual results indicated that leadership quality does moderate the relationship between market focus and performance of organization as well as that between market planning and performance of organization.
