A transmission tower or pylon (also known as an ironman in Australia and a hydro tower in parts of Canada) is a tall tower used for electric power transmission. It carries the electrical conductors (wires) of high-voltage overhead power lines. The tower is high for a safe distance for people, animals or things below the wires.

Most big transmission towers are lattice steel structures. Smaller ones may be wood, concrete or steel poles.
