Terrorism constitutes one of the most important security issues of the period experienced. The fight against terrorism as a serious threat at humanitarian, national, regional and international levels, and against terrorist organizations, whose capabilities and capabilities have shown an unusual development, also stands out as a serious problem in this context. This study examines the role of open source intelligence in the fight against terrorism. There are many methods and techniques used in intelligence gathering. What makes open source intelligence special is its advantage in terms of cost, accessibility, legality and risk in collection activities. In the fight against terrorist organizations, those gathered from open sources are important inputs that make the intelligence circle operational. In the study, first of all, a broad framework will be drawn on intelligence gathering and open source intelligence. Thus, it is planned to make a modest contribution to the Turkish literature on this subject. In the second part, the role of intelligence in counterterrorism applications and the importance of open source analysis in collection activities will be tried to be revealed. Here, what, how and to what extent can be gathered regarding terrorist organizations and their activities will be expressed. The study will end with an evaluation that includes the dark internet.
