A utility pole is a column or post used to support overhead power lines and various other public utilities, such as cable, fibre optic cable, and related equipment such as transformers and street lights. It can be referred to as a transmission pole, telephone pole, telecommunication pole, power pole, hydro pole,telegraph pole, or telegraph post, depending on its application. A stobie pole is a multi-purpose pole made of two steel joists held apart by a slab of concrete in the middle, generally found in South Australia.
Electrical cable is routed overhead on utility poles as an inexpensive way to keep it insulated from the ground and out of the way of people and vehicles. Utility poles can be made of wood, metal, concrete, or composites like fiberglass. They are used for two different types of power lines; subtransmission lines which carry higher voltage power between substations, and distribution lines which distribute lower voltage power to customers.
Utility poles were first used in the mid-19th century with telegraph systems, starting with Samuel Morse who attempted to bury a line between Baltimore and Washington, D.C., but moved it aboveground when this system proved faulty. Today, underground distribution lines are increasingly used as an alternative to utility poles in residential neighborhoods, due to poles' perceived ugliness.

As Atlantic Electric linemen were extinguishing a fire atop a utility pole in Wildwood Crest, a series of explosions took place, which resulted in a power outage. No one was injured in the April 1, 2008 mishap, which occurred about 8:15 p.m. Due to a fog rolling in, it was possible that the salt air induced arcing when it was bombarded with the electrical energy emanating from the wires. An utility worker in a sky-arm truck was attempting to extinguish a fire atop the pole when it ignited and then exploded. Wildwood fire stations were summoned to Wildwood Crest firehouse to standby as Wildwood Crest firefighters remained on the scene of the event. Traffic was diverted one block within all directions.
