The Mercedes-AMG G 63 6x6 or Mercedes-Benz G 63 AMG 6x6 is an SUT manufactured by Mercedes-Benz. An SUT derivative of the six wheel drive Mercedes Geländewagen developed for the Australian Army from 2007 (see G-Class Military operators), at the time it was the company's largest offroad vehicle and second most expensive street-legal model after only the SLS AMG Electric Drive. It was manufactured from 2013 to 2015 by Magna Steyr in Graz, Austria.

It combines the engine from the G63, a twin-turbo V8, with 6x6 portal axles, a pick-up version of the G-Class body, and a luxury interior. It was produced from 2013 to 2015, with production exceeding 100 vehicles.

An extra shaft delivers power to the rearmost axle. The vehicle has five electronic differential locks, which can deliver 100% lockup of all six wheels, operated by three switches on the dashboard.
