The International DuraStar, originally introduced as the International 4000 Series, is a medium-duty truck produced by Navistar International. First produced in 2002, it is the successor to the 4000 Series of the 1990s.

It is available in three variants, which are built on the same chassis. They differ in engines, drivetrains, brakes, and cargo capacity. It is a popular commercial platform used in a wide variety of applications, such as emergency services, towing, flatbed truck and as a cargo box truck. Variants of the Durastar are commonly used as a platform for both school buses and commercial buses.
