We present dyonic multi-membrane solutions of the N=2 D=8 supergravity theory that serves as the effective field theory of the T2-compactified type II superstring theory. The `electric' charge is fractional for generic asymptotic values of an axion field, as for D=4 dyons. These membrane solutions are supersymmetric, saturate a Bogomolnyi bound, fill out orbits of an Sl(2;\Z) subgroup of the type II D=8 T-duality group, and are non-singular when considered as solutions of T3-compactified D=11 supergravity. On K3 compactification to D=4, the conjectured type II/heterotic equivalence allows the Sl(2;\Z) group to be reinterpreted as the S-duality group of the toroidally compactified heterotic string and the dyonic membranes wrapped around homology two-cycles of K3 as S-duals of perturbative heterotic string states.
