  We consider single charged Higgs ($H^{\pm}$) and pseudoscalar Higgs ($A^0$)
production in association with a gauge boson at $\mu^+\mu^-$ colliders. We find
that the tree-level t-channel and s-channel contributions to $\mu^+\mu^-\to
H^{\pm}W^{\mp}, A^0Z$ are enhanced for large values of $\tan\beta$, allowing
sizeable cross-sections whose analogies at $e^+e^-$ colliders would be very
small. These processes provide attractive new ways of producing such particles
at $\mu^+\mu^-$ colliders and are superior to the conventional methods in
regions of parameter space.
