Chronology
PredecessorInternational 3800
SuccessorInternational MV (bus chassis)

The International 3300 is a Type-C (conventional-style) cowled bus chassis manufactured by Navistar International from the 2005 to the 2024 model years, derived from the International DuraStar for the United States, Canada, and Mexico. While most examples were produced as yellow school buses, variants of the 3300 were also produced for commercial applications; International also produced a cutaway-cab variant of the model line.

Developed as the successor to the International 3800 (the final model line of the International S series), the 3300 is a derivative of the International 4300 medium-duty truck (later renamed the DuraStar, succeeded by the International MV in 2019). The 3300 was produced from 2004 until 2023, when it was replaced by the cowled bus chassis version of the MV.
