Abstract: Let $ f$ and $ g$ be functions, not identically zero, in the Fock space $ F^2_\alpha $ of $ \mathbb{C}^n$. We show that the product $ T_fT_{\overline g}$ of Toeplitz operators on $ F^2_\alpha $ is bounded if and only if $ f(z)=e^{q(z)}$ and $ g(z)=ce^{-q(z)}$, where $ c$ is a nonzero constant and $ q$ is a linear polynomial.
