Introduction: Nowadays, improvement of security levels in public spaces around the world is considered as one of the most important issues for managers, planners and urban designers. Parks can be very effective, particularly from the viewpoint of urban planners, in increasing or decreasing sense of security. They are one of the most important components of urban and natural systems and their characteristics such as location, design, accessibility, lighting, construction, population, etc. should be considered seriously in urban planning. Urban parks have scattered trees with synthetic or natural grass. They are the most popular place for human recreation and usually provide a pleasant environment for citizens to get involved in social activities, comfort, leisure, family affairs. This paper explored the security level of parks in Qom's 2nd district as one the most populated destinations of travelers in the city. As for defining the term security, different sources have different definitions. For example, Moein's dictionary defines security as something which is safe, secure and immune, without fear. Likewise, in Amid dictionary, security is defined in terms of comfort, convenience and safety, which above all, is said to have an important role in the origin of city life in modern time, especially in public places.
