We study the muon anomalous magnetic moment 
in the context of the reduced minimal 3-3-1 model recently proposed in the literature. In particular, its spectrum contains a doubly charged scalar (
) and gauge boson (
), new singly charged vectors (
) and a 
boson, each of which might give a sizeable contribution to the . We compute the 1-loop contributions from all these new particles to the . We conclude that the doubly charged vector boson provides the dominant contribution, and by comparing our results with the experimental constraints we derive an expected value for the scale of 
symmetry breaking 
TeV. We also note that, if the discrepancy in the anomalous moment is resolved in the future without this model then the constraints will tighten to requiring 
TeV with current precision, and they will entirely rule out the model if the expected precision is achieved by the future experiment at Fermilab.
