The Bogomolnyi vortex of the N=2 supersymmetric abelian-Higgs model in 2+1 dimensions is shown to be a "semion" of spin 1/4. Specifically, the effective superparticle action for one vortex is shown to describe, upon quantization, a parity self-dual centrally-charged 'short' supermultiplet of "relativistic helicities" (-1/4,-1/4, 1/4,1/4).
