A model commercial vehicle is a scale model that represents a commercial vehicle -- truck (lorry), bus, etc. -- generally reproducing actually produced vehicles.

Like model cars, model commercial vehicles are sold both as kits for the enthusiast to construct and paint and as pre-built, pre-painted collectable models. Model kits may be made in plastic, resin, metal (including white metal), and wood; collectables are usually made of die-cast metal and plastic. One of the most used alloys is Zamac, a combination of Zinc and Aluminium. Z.A.M.A.C. :Zinc and Aluminium Metal Alloy Casting.

Enthusiasts may pursue commercial vehicle modeling in its own right or as an adjunct to model railways, where the vehicles add verisimilitude to a layout (for example: trucks in a goods yard; buses at a station). The most popular die cast scales for commercial vehicles are 1/43 and 1/50, coming from their initial role as props in O scale model railway layouts. When O scale became less popular for trains, giving way to HO, the 1/43 and 1/50 scales grew and prospered for die cast commercial vehicles.
