Proton decay in three-generation superstring models with intermediate scale is investigated. It is shown that matter-parity (M/sub 2/) invariance alone does not stabilize the proton. However, models with M/sub 2/ invariance and Calabi-Yau manifolds such that the exotic C-odd quarks and leptons are superheavy will generally lead to proton lifetimes consistent with existing data.
