The Chevrolet Kodiak and GMC TopKick are a range of medium-duty trucks that were produced by the Chevrolet and GMC divisions of General Motors from 1980 to 2009. Introduced as a variant of the medium-duty C/K truck line, three generations were produced. Slotted between the C/K trucks and the GMC Brigadier Class 8 conventional, the Kodiak/TopKick were developed as a basis for vocationally oriented trucks, including cargo haulers, dump trucks, and similar vehicles; on later generations, both cutaway and cowled-chassis variants were produced for bus use.

Following years of declining market share, General Motors (in line with Ford Motor Company) sought to exit heavy-truck manufacturing. After struggling to enter joint ventures or sell the rights to its product line, the company ended production of the Kodiak and TopKick in 2009. The final medium-duty truck, a GMC TopKick 5500, rolled out of Flint Truck Assembly on July 31, 2009.

For the 2019 model year, after a ten-year hiatus, General Motors re-entered the conventional medium-duty truck segment. Developed in a joint venture with Navistar International, the Chevrolet Silverado 4500/5500 is a Class 4–6 vehicle. Slightly smaller than the Kodiak/Topkick, the Silverado 4500/5500 is marketed exclusively as a Chevrolet (with no GMC counterpart).
