  Trilinear couplings of the neutral CP-even Higgs bosons in the Minimal
Supersymmetric Standard Model (MSSM) can be measured through the multiple
production of the lightest CP-even Higgs boson (h) at high-energy e^+e^-
colliders. This includes the production of the heavier CP-even Higgs boson (H)
via e^+e^- \to ZH, in association with the CP-odd Higgs boson (A) in e^+e^- \to
AH, or via e^+e^- \to \nu_e \bar\nu_e H, with H subsequently decaying through H
\to hh. These processes can enable one to measure the trilinear Higgs couplings
\lambda_{Hhh} and \lambda_{hhh}, which can be used to theoretically reconstruct
the Higgs potential. We delineate the regions of the MSSM parameter space in
which these trilinear Higgs couplings could be measured.
