边境管制是国家或地区，进行管制或监察边境流量的措施。

依世界各国通例，国际机场或港口之检查，系采C、I、Q制度：海关（Customs），负责货物进出口的管制及旅客行李及国际邮包的检查；移民机关（Immigration），负责人员的出入境管理与管制及证照查验；检疫机关（Quarantine），负责入境人员及进出口货物（含跨境动植物）之检疫工作。及边防机构及海岸防卫队负责边境治安。这类执法人员的官方名称视乎当地情况。

Border controls are measures taken by a country to monitor or regulate its borders. Border controls are put in place to control the movement of people, animals and goods into as well as out of a country. Specialized government agencies are usually created to perform border controls. Such agencies may perform various functions such as customs, immigration, security, quarantine, beside other functions. Official designations, jurisdictions and command structures of these agencies vary considerably.
