The complex scaling theory is successfully used in atomic and molecular physics. This method is generalized to the Dirac equation. It is shown that Dirac resonances are associated with nonreal eigenvalues of the scaled Dirac Hamiltonian, which describes a free particle with spin 1/2 and rest mass m in relativistic quantum mechanics. The perturbation theory for Dirac resonances is reduced to the standard Kato-Rellich theory.
