The International 9000 Series is a range of trucks that was manufactured by Navistar International (previously International Harvester) from 1971 to 2017. A conventional-cab truck, the model range was configured primarily for highway applications. In terms of size, the model range was slotted between the medium-duty Loadstar (and the S-Series that replaced it) and severe-service Paystar series.

Through its production, International Harvester (and later Navistar) produced the model line in three distinct generations. Offered in multiple layouts, the Transtar 4000/9000 series was offered with single or tandem drive axles, multiple hood lengths, and multiple cab configurations (day cabs or various sizes of sleeper cabs).

During the 2000s, International phased out much of the model line in favor of the NGV-cab ProStar and LoneStar model lines; after a 46-year production run, the final 9900i was produced in 2017.
