We find a large CP violation effect within the two-Higgs-doublet model for the reaction e+e^\mathrm\ensuremath-\ensuremath→tt\ifmmode\else\textasciimacron\fiH0 at future linear colliders. The CP asymmetry arises already at the tree level as a result of interference between diagrams with H0 emission from t (and t\ifmmode\else\textasciimacron\fi) and its emission from a Z0 and can be about 10--20 %. In the best case one needs a few hundred tt\mathit\ifmmode\else\textasciimacron\fiH0 events to observe CP violation at the 3\ensuremathσ level. \textcopyright 1996 The American Physical Society.
