The Lincoln MKX is a mid-size luxury crossover SUV marketed and sold by the Lincoln brand of Ford Motor Company. As Lincoln is phasing out its use of "MK" model names, the MKX adopted the Lincoln Nautilus nameplate as part of a mid-cycle update for the 2019 model year. In production since 2007, the MKX ("X" stands for "crossover") is the first crossover SUV offered by the Lincoln brand; it is currently in its second generation. Initially the smallest Lincoln SUV, it is now slotted between the Lincoln Corsair and the Lincoln Aviator. The Lincoln counterpart of the Ford Edge CUV across both generations, the MKX has been the best-selling Lincoln model line since 2016.
