The Xbox 360 controller is the primary game controller for Microsoft's Xbox 360 home video game console that was introduced at E3 2005. The Xbox 360 controller comes in both wired and wireless versions.[ The Xbox controller is not compatible with the Xbox 360. The wired and wireless versions are also compatible with Microsoft PC operating systems, such as Windows XP, Windows Vista, Windows 7, Windows 8, and Windows 10.

The wireless controllers run on either AA batteries or a rechargeable battery pack. The wired controllers may be connected to any of the USB ports on the console, or to an attached USB hub.

The Xbox 360 controller has the same basic familiar button layout as the Controller S except that a few of the auxiliary buttons have been moved. The "back" and "start" buttons have been moved to a more central position on the face of the controller, and the "white" and "black" buttons have been removed and replaced with two new bumpers that are positioned over the analog triggers on the back of the controller. The controller has a 2.5 mm TRS connector on the front, allowing users to connect a headset for voice communication.[ It also features a proprietary serial connector (which is split into 2 parts on either side of the headset connector) for use with additional accessories, such as the chatpad.

A standard Xbox 360 controller features eleven digital buttons, two analog triggers, two analog sticks and a digital D-pad. The right face of the controller features four digital action buttons: a green  button, red  button, blue  button, and yellow  button. The lower right houses the right analog stick, in lower left is a digital D-pad and on the left face is the left analog stick. Both analog sticks can also be clicked in to activate a digital button beneath. In the center of the controller face are digital "Start", "Back" and "Guide" buttons. The "Guide" button is labelled with the Xbox logo, and is used to turn on the console/controller and to access the guide menu. It is also surrounded by the "ring of light", which indicates the controller number, as well as flashing when connecting and to provide notifications. The left and right "shoulders" each feature a digital shoulder button, or "bumper", and an analog trigger.

Wireless controllers also feature an additional "connect" button located between the "bumpers" to facilitate syncing with the console.
