It is known that if j:M --> S3 is a branched covering branched along the p, q-torus knot, then M is a Seifert manifold with orientable base and non-zero Euler number. We prove a converse of this fact: If M is an orientable Seifert manifold with orientable base and non-zero Euler number, then M is a branched covering of the 3-sphere with branching in the p, q-torus knot for any p, q, (p, q)=1, and 1 < p < q.
