In [[computing]] and especially in [[computer hardware]], a '''controller''' is a [[Integrated circuit|chip]], an [[expansion card]], or a stand-alone device that [[interface (computing)|interface]]s with a [[peripheral]] device. This may be a link between two parts of a computer (for example a [[memory controller]] that [[memory management|manages access to memory]] for the computer) or a controller on an external device that manages the operation of (and connection with) that device.

The term is sometimes used in the opposite sense to refer to a device by which the user controls the operation of the computer, as in ''[[game controller]]''.
