The Iveco Zeta was a light to medium-duty truck model produced by the Italian manufacturer Iveco. Appearing in 1976 and entering production in 1977, it continued the lineage begun the OM Lupetto, which was introduced in 1959. The Lupetto, as well as the Leoncino, the Daino, and the Tigrotto, were all replaced by the OM X-series in 1972, which then formed the basis for the Zeta range. The Zeta itself was replaced by the all-new Iveco Eurocargo in 1991.
