The Jeep FJ-3 Fleetvan was a compact delivery van manufactured by Willys Motors and Kaiser-Jeep from 1961 to 1965. It was based on the DJ-3A Dispatcher, but equipped with the F-134 Hurricane engine. Two models were available, the FJ-3 and the longer FJ-3A. It came standard with the familiar Borg-Warner T-90 three-speed manual transmission. A Borg-Warner automatic was offered as an option.

Right-hand-drive FJ-3s were made for the U. S. Postal Service. Most of these had horizontal grille slats in contrast to the seven vertical slats found on standard models.

An FJ-6 model was introduced in 1965 for postal use, which was ultimately replaced by the FJ-9 introduced in 1975.
