Non-government organizations (NGOs) have played a pivotal role in community development and nation building in the Philippines. However, there is a paucity of literature on the leadership behaviors of NGO leaders and how these influence performances of NGOs in the country. This study aimed to determine leadership behavior of selected NGO directors in Iligan and Cagayan de Oro City in Northern Mindanao Philippines. The Leader Behavior Description Questionnaire, a previously validated questionnaire, was used in this study. Approval from four selected NGOs in Northern Mindanao was sought prior to the collection of data. These NGOs were selected based on their common goal of achieving the Millennium Development Agenda. Informed consent was obtained from 100 participants of these NGOs. Data from the questionnaire was analyzed using descriptive statistics. Findings showed that the most common leadership behavior was Considerate, Facilitative, Autocratic and Participative Leadership behaviors. Findings suggest that NGO leaders in Northern Mindanao tend to involve members during decision-making and place a high value on the contributions of the members. Findings could form baseline data on leadership behaviors of NGO leaders in Northern Mindanao. It is recommended that associations between leadership behavior and performances of the NGOs should be investigated in future studies.
