The utility model provides an unattended LNG (Liquefied Natural Gas) filling station. The unattended LNG filling station comprises an LNG storage tank, a pump skid, a gas filling machine and a controller, the controller can control on-off of the immersed pump, on-off of the first switch valve and on-off of the second switch valve. After the controller receives a liquid adding signal, the immersed pump can be controlled to be started and the first switch valve and the second switch valve can be controlled to be switched on, so that a driver of the LNG vehicle can charge the LNG in a self-service mode, a gas station does not need to be specially provided with filling personnel and cashier personnel, the operation safety is guaranteed, meanwhile, the filling efficiency can be improved, the personnel investment is reduced, and the working efficiency is improved. The construction cost of the gas station is reduced, and the automation degree of the gas station is improved. 本实用新型提供了一种无人值守LNG加气站，该无人值守LNG加气站包括LNG储罐、泵撬
