We have calculated the mass spectra of nucleon and delta hybrid baryons with both positive-parity and negative-parity by using the method of QCD sum rules. We predicte that the lowest-lying hybrid baryons are the negative-parity N1/2- and Δ1/2- states, while the positive-parity ones are much heavier. We suggest to search for these light hybrid baryons via the χcJ/Υ decay processes in the future.
