We study the associated production of the charged Higgs boson and W^\ifmmode±\else\textpm\fi gauge boson in high energy e+e^\ensuremath- collisions in the minimal supersymmetric standard model (MSSM). This associated production, which first arises at the one loop level, offers the possibility of producing the charged Higgs boson at the e+e^\ensuremath- collider with a mass more than half the center-of-mass energy, when the charged Higgs pair production is kinematically forbidden. We present analytic and numerical results for the cross section for e+e^\ensuremath-\ensuremath→W+H^\ensuremath- in the full MSSM, taking into account the previously uncalculated contributions from supersymmetric (SUSY) particles. We find that the contributions of the SUSY particles enhance the cross section over most of SUSY parameter space, especially when the SUSY particles are light, \ensuremath∼200 GeV. With favorable SUSY parameters, at small tan\ensuremathβ, this process can yield more than ten W^\ifmmode±\else\textpm\fiH^\ensuremath∓ events for m_H^\ifmmode±\else\textpm\fi\ensuremath\lesssim350 GeV in 500 fb^\ensuremath-1 at a 500 GeVe+e^\ensuremath- collider, or m_H^\ifmmode±\else\textpm\fi\ensuremath\lesssim600 GeV in 1000 fb^\ensuremath-1 at a 1000 GeV collider. 80% left-handed polarization of the e^\ensuremath- beam improves these reaches to m_H^\ifmmode±\else\textpm\fi\ensuremath\lesssim375 GeV and m_H^\ifmmode±\else\textpm\fi\ensuremath\lesssim670 GeV, respectively.
