The International Harvester Fleetstar is a series of trucks that was produced between 1962 and 1977 by International Harvester. Slotted above the Loadstar and below the Paystar and Transtar conventionals introduced after it, the Fleetstar was a heavy-duty truck; it was one of the first designed for vocational use. Using a conventional-cab configuration, the Fleetstar was available as both a straight truck and as a semitractor, with both single and tandem rear axles.
