Chrysler Group LLC ( /ˈkraɪslər/) is an American-based, multinational automaker, in global strategic alliance with its majority owner, Italian manufacturer Fiat, since 2009.

Chrysler was first organized as the Chrysler Corporation in 1925. Its core brands which it produces are Chrysler, Jeep, Dodge, Ram, SRT, Fiat, and Mopar vehicles and products. The Company is headquartered in Auburn Hills, Michigan, United States.

On June 10, 2009, Chrysler LLC emerged from a government backed Chapter 11 reorganization as Chrysler Group LLC, in alliance with the Italian automaker Fiat. Initially holding a 20% interest in Chrysler Group, Fiat's stake was increased to 58.5% (fully diluted) following acquisition of the equity interests held by the U.S. Treasury (6% on June 3, 2011) and Canada (1.5% on July 21, 2011)

The company was founded by Walter Chrysler (1875–1940) on June 6, 1925, when the Maxwell Motor Company (est. 1904) was re-organized into the Chrysler Corporation.

Walter Chrysler arrived at the ailing Maxwell-Chalmers company in the early 1920s. He was hired to overhaul the company's troubled operations (after a similar rescue job at the Willys-Overland car company). In late 1923 production of the Chalmers automobile was ended.
