Energy-dependent global Dirac optical model potentials are found by fitting proton elastic scattering data in the energy range 20--1040 MeV for [sup 12]C, [sup 16]O, [sup 40]Ca, [sup 90]Zr, and [sup 208]Pb. Three different energy- and atomic-mass-number-dependent global Dirac optical potentials are also obtained. A number of characteristic features of the potentials are discussed. In addition, the mean free path, the effective mass [ital m][sub [ital e]][sup *], the Dirac mass [ital M][sup *], and the relativistic energy shift [ital E][sup *] are calculated.
