There are few reports on impact craters in Saudi Arabia. This paper aims to fill a gap in the literature in this area. Using satellite imaging, a circular structure with a diameter of approximately 15 kilometers was detected on the edge of Harrat Rahat volcanic field in western Saudi Arabia. Fieldwork showed that the circular structure is a newly-discovered comet impact crater candidate, this theory is aided by the presence of shock metamorphic features such as planar fractures in quartz grains and impact breccia. This impact crater candidate could be one of the largest exposed and preserved impact craters in Saudi Arabia.
