The decay J/psi -> omega p (p) over bar has been studied, using 225.3 X 10(6) J/psi events accumulated at BESIII. No significant enhancement near the p (p) over bar invariant-mass threshold [denoted as X(p (p) over bar)] is observed. The upper limit of the branching fraction B(J/psi -> omega X(p (p) over bar) -> omega p (p) over bar is determined to be 3.9 X 10(-6) at the 95% confidence level. The branching fraction of J/psi -> omega p (p) over bar is measured to be B(J/psi -> omega p (p) over bar) = (9.0 +/- 0.2(stat) +/- 0. 9(syst) X 10(-4).
