General Dynamics Land Systems (GDLS) is an American manufacturer of military vehicles, including tanks and light Armoured fighting vehicles. The company is based in Sterling Heights, Michigan, and is a subsidiary of General Dynamics.

It was originally established in 1982 following the acquisition of Chrysler Defense.

GDLS is known for developing and manufacturing vehicles such as the M1 Abrams tank, Stryker, and LAV 6.

In February 1982, Chrysler announced the sale of Chrysler Defense, its profitable defense subsidiary, to General Dynamics for US$348.5 million. The sale was completed in March 1982 for the revised figure of US$336.1 million and renamed General Dynamics Land Systems. Under this newly formed division, General Dynamics would take over production of the M60 and M1 tanks for the United States Army.

In 1985, 3 years after the sale from Chrysler, General Dynamics production plants in Ohio, Michigan and Pennsylvania went on strike. Members of these plants were part of the United Automobile Workers union. The strike was primarily around wage increases.

On April 11, 2024, the Chinese Foreign Ministry announced sanctions on the company due to its arms sales to Taiwan. On March 4, 2025, the Chinese Ministry of Commerce placed 15 U.S. entities (including General Dynamics Land Systems) on its export control list, barring the export of dual-use commodities to that business.

General Dynamics Land Systems–Australia (GDLS-Australia or GDLS-A) was established in 2000 as a subsidiary to support the production of ASLAV. GDLS-A now provides engineering, manufacturing, systems integration, upgrade and fleet management services for GDLS Armoured Fighting Vehicles in the Asia Pacific region. In Australia this includes the ADF's ASLAV Light Armoured Vehicles and M1A1 Main Battle Tanks, supported under a Through Life Support Contract awarded in June 2011.

GDLS-A reports operationally to General Dynamics Land Systems–Canada (GDLS-C).
