We propose magnetic proto-neutron star (PNS) winds driven by Alfvén waves as well as the neutrino heating as an appropriate site for the r-process nucleosynthesis. Alfvén waves excited by surface motions of a PNS propagate outwardly, and they heat and accelerate the wind by dissipation. In the Alfvén wave-driven wind, larger entropy per baryon and shorter dynamical time scale are achieved, which favors the r-process. A PNS with surface B0 > ∼ 5× 1014G, gives suitable wind properties for the r-process in a typical case. We also perform nuclear reation calcuations and confirm this result; the 3rd peak elements are sufficiently synthesized in the Alfvén wavedriven wind in such a condition.
