To see whether a heavy baryon and an antibaryon can form a bound state, the heavy baryonium, we study the two-pion exchange interaction potential between them within the heavy baryon chiral perturbation theory. The obtained potential is applied to calculate the heavy baryonium masses by solving the Schr"odinger equation. We find it is true that the heavy baryonium may exist in a reasonable choice of input parameters. The uncertainties remaining in the potential and their influences on the heavy baryonium mass spectrum are discussed.
