The Chevrolet Kodiak (and similar GMC TopKick and Isuzu H-Series) is a line of medium duty trucks from General Motors. It was produced from 1980 to 2009, when General Motors exited the medium-duty truck market.

The Kodiak/TopKick were commonly used as a basis for work trucks, cargo haulers, dump trucks, and similar vehicles which required medium duty torque, GVWR, towing capacity. There are aftermarket coachbuilders that built them as pickup trucks and commercial trucks for consumers.

The Kodiak and TopKick were introduced in 1980 as stronger versions of GM's existing medium-duty C-Series trucks. "Kodiak" followed the pattern of "frontier beast" names given to heavier trucks such as the Chevrolet Bison and Chevrolet Bruin, while "Top Kick" came from military slang and tied in with GMC's heavy truck names of General and Brigadier. First-generation models can be distinguished by a full-width grille with quad square headlights arranged horizontally in chrome bezels underneath with the GMC lettering or Chevy "bowtie" above the grille; normal 1973–89 C50-C80s had single round headlights and the emblem all incorporated into the grille area.
