The Chrysler 300M is a full-size luxury car that was produced by Daimler/Chrysler from 1999 to 2004. It is a front-wheel drive, 255 hp V6 engined car using the Chrysler LH platform. Versus its platform mates, the 300M was roughly 10 inches (25 cm) shorter to make it more easily exportable to Europe. Priced above the Concorde and identically to the LHS, the 300M shared Chrysler's flagship position with the LHS until the LHS's discontinuation after 2001, upon which it became Chrysler's sole flagship model.

The LH platform served as the basis for the Chrysler Concorde, Chrysler LHS, Chrysler 300M, Dodge Intrepid, Eagle Vision, and the final Chrysler New Yorker. A Plymouth to be called the "Accolade" was planned, but never saw production. The platform pioneered Chrysler's "cab-forward" design; featured on some Chrysler, Dodge, and Eagle cars in the 1990s and early 2000s.
