The role of the form factor and short-range correlation in nuclear matter is studied within the relativistic Hartree-Fock approximation. We take, first, the mean-field approximation for meson fields and obtain the fluctuation terms of mesons to be used for the Fock energies. We introduce form factors in the meson-nucleon coupling vertices to take into account the finite-size effect of the nucleon. We use further the unitary correlation operator method for the treatment of the short-range correlation. The form factors of the size ( 
∼ 1.0 -2.0GeV) of the nucleon-nucleon interaction cut down largely the contribution of the 
-meson in the Fock term. The short-range correlation effect is not large but has a significant effect on the pion and -meson energies in the relativistic Hartree-Fock approximation for nuclear matter.
