The Chevrolet Tahoe, and its badge-engineered GMC Yukon counterpart, are full-size SUVs and other trucks from General Motors, offered since 1994 and 1991, respectively. Since 1982, Chevrolet and GMC sold two different-sized SUVs under their "Blazer" and "Jimmy" nameplates, by introducing the smaller S-10 Blazer and GMC S-15 Jimmy for the 1983 model year, below the full-size Blazer and Jimmy models. This situation lasted into the early 1990s. GMC first rebadged the full-size Jimmy as the "Yukon" in 1991. Chevrolet however waited until 1994, when they rebadged the redesigned mid-size S-10 Blazer the "new Blazer," while renaming the full-size Blazer as the "Tahoe." The name Tahoe refers to the rugged and scenic area surrounding Lake Tahoe in the western United States, and was originally used as a trim level on S-10 models. The name Yukon refers to the Yukon territory of northern Canada.

A sport utility vehicle (SUV) is a car classification that combines elements of road-going passenger cars with features from off-road vehicles, such as raised ground clearance and four-wheel drive.
