The Lincoln MKX is a mid-size luxury crossover SUV[1][2] manufactured by Ford Motor Company and marketed its Lincoln brand over two generations, as a rebadged variant of the Ford Edge crossover, for both generations.

The production model received the MKX nameplate, with Lincoln management suggesting a "mark ex" pronunciation during the 2006 auto show circuit, subsequently changed to the phonetic M-K-X.

[4] Due to the similarity of the MKX name to the MDX name used by Acura for their competing luxury crossover, Honda, Acura's parent company, filed a lawsuit against Ford in January 2006, eventually settling the case out of court.

The MKX features an optional adaptive headlight system that pivots the aim of the light projectors to match the steering inputs of the driver.

The sole powertrain in the MKX is an all-aluminum, 3.7-liter Duratec DOHC V6 mated to Ford's 6F50 6-speed automatic transmission.

[7] For 2008 changes for the MKX included Lincoln badges added near the front doors as well as Ford Sync, Limited Edition and Monochromatic Limited Edition packages with unique styling elements and 20-inch chrome wheels, and a voice-activated DVD navigation system.

The 2011 MKX featured the first application of the all-new MyLincoln Touch driver connect technology system.

The MKX offers the "Thoroughbred" (shared with the MKZ and the Continental), "Modern Heritage", and "Indulgence" theme appearance packages.

For the 2019 model year, the second-generation MKX underwent a mid-cycle revision that was introduced in November 2017, taking on the Lincoln Nautilus nameplate.
