The Chevrolet Tahoe, and its badge engineered GMC Yukon counterpart, are full-size SUVs 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 as their '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. The name Yukon refers to the Yukon territory of northern Canada.

For the 1995 model year, the Tahoe and Yukon gained a new, longer four-door model, slotting in size between the two-door models and the longer wheelbase Chevrolet/GMC Suburbans.

The Tahoe is sold in North America, parts of Asia such as the Philippines and the Middle East, plus other countries including Bolivia, Chile, Peru, Colombia, Ecuador, and Angola as a left-hand drive vehicle. The Yukon is only sold in North America and the Middle East.

The Chevrolet Tahoe and GMC Yukon are part of General Motors' full-size SUV family and are differentiated from the similar Chevrolet Suburban and GMC Yukon XL primarily by the length of the passenger and cargo area behind the C pillar. An upscale trim GMC Denali sub-model joined the Yukon lineup as the top-of-the-line trim for the 1999 model year; the Cadillac Escalade is a closely related upscale version sharing the same platform. The Denali is available on both standard and XL versions.
