The Mössbauer effect and ab initio investigations of an electric field gradient at ^{57}Fe nuclei in Pt_3Fe compound are presented. It is shown that nonzero ^{57}Fe electric field gradient exists in the cubic Pt_3Fe. Ab initio study of Pt_3Fe in antiferromagnetic state confirms the presence of electric field gradient at ^{57}Fe nuclei. Lattice, local valence electron (3d, 4p) and weakly bound 3p core electron contributions to electric field gradient are separated out and discussed in the context of the electronic structure changes upon the antiferromagnetic phase transition.
