The Jaguar Advanced Lightweight Coupe (ALC) is a sports coupé concept car first shown at the 2005 North American International Auto Show in Detroit by the British automobile manufacturer Jaguar, then part of Ford's Premier Automotive Group.

Designed by Ian Callum and Giles Taylor the concept previewed the Jaguar XK[1] which was subsequently launched at the autumn 2005 Frankfurt Motor Show.

The hatchback design, 2+2 seating layout and the bonnet harkened back to its predecessor, the XK8.

The aluminium chassis shared with the XJ saloon and all-aluminium construction were a first for a Jaguar grand tourer.

An Alpine telematics system is present on the centre console which controls most of the car's functions.
