A fire hydrant, also called a fireplug, fire pump, jockey pump, or simply pump, is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection.

The user attaches a hose to the fire hydrant, then opens a valve on the hydrant to provide a powerful flow of water, on the order of 350 kPa (50 pounds per square inch gauge (psig)) (this pressure varies according to region and depends on various factors including the size and location of the attached water main). This user can attach this hose to a fire engine, which can use a powerful pump to boost the water pressure and possibly split it into multiple streams. One may connect the hose with a threaded connection, instantaneous “quick connector” or a Storz connector. A user should take care not to open or close a fire hydrant too quickly, as this can cause a water hammer, which can damage nearby pipes and equipment.

In the United Kingdom and Ireland, hydrants are located in the ground. Yellow “H” hydrant signs indicate the location of the hydrants, and are similar to the blue signs in Finland. In Australia, hydrant signage varies, with several types displayed across the country. Most Australian hydrants are underground, being of a ballcock system (spring hydrant type), and a separate standpipe with a central plunger is used to open the valve.

In Germany the hydrant marker plates follow the style of other marker plates pointing to underground installations. Fire hydrant marker plates have a red border. Other water hydrants may have a blue border.
In East Asia (China, Japan and South Korea) and former Socialist countries of Eastern Europe, there are two types of fire hydrants, of which one is on the public ground and the other inside a building. The ones inside a building are installed on a wall. They are big, rectangular boxes that also provide alarms (sirens), a fire extinguisher and, at certain times, emergency kits.
