受电杆（旧称集电杆），是支撑受电头并向或触靴传递弹簧压力、具有一定挠性的管或杆。受电杆是一种杆形受电器，通过活动杆上安装的触轮和触靴从架空接触网的接触线上获取电流。

受电杆的末端称为受电头，包括触靴、支持机构并且允许触靴作必要运动。触靴内嵌由石墨制成的炭滑块，中央有一凹槽，用以压紧接触线并滑动而能获取电流。受电杆一般用于无轨电车和老式有轨电车，安装于车顶受电杆座上，基部凭借弹簧支撑并通过受电杆枢轴实现一定程度的转动。受电杆弹簧向上的张力把受电杆顶在架空接触网的接触线之下，并保持触靴与接触线的接触。金属制造的受电杆一般会在受电杆座绝缘，实心者通过电杆本身，空心者内嵌导线导电。

A trolley pole is a tapered cylindrical pole of wood or metal, used to transfer electricity from a "live" overhead wire to the control and the electric traction motors of a tram or trolley bus. It is a type of current collector. The use of overhead wire in a system of current collection is reputed to be the 1880 invention of Frank J. Sprague, while the first working trolley pole was developed and demonstrated by Charles Van Depoele, in autumn 1885.
