A filling station (also known as a gas station [US] or petrol station [UK]) is a facility that sells fuel and engine lubricants for motor vehicles. The most common fuels sold in the 2010s were gasoline (or petrol) and diesel fuel.

Gasoline pumps are used to pump gasoline, diesel, compressed natural gas, CGH2, HCNG, LPG, liquid hydrogen, kerosene, alcohol fuel (like methanol, ethanol, butanol, and propanol), biofuels (like straight vegetable oil and biodiesel), or other types of fuel into the tanks within vehicles and calculate the financial cost of the fuel transferred to the vehicle. Besides gasoline pumps, one other significant device which is also found in filling stations and can refuel certain (compressed-air) vehicles is an air compressor, although generally these are just used to inflate car tires.

Many filling stations provide convenience stores, which may sell confections, alcoholic beverages, tobacco products, lottery tickets, soft drinks, snacks, coffee, newspapers, magazines, and, in some cases, a small selection of grocery items, such as milk. Some also sell propane or butane and have added shops to their primary business. Conversely, some chain stores, such as supermarkets, discount stores, warehouse clubs, or traditional convenience stores, have provided fuel pumps on the premises.
