Using a data sample of 1.06×10⁸ ψ' events collected with the BESIII detector in 2009, the branching fractions of χcJ→pn̄π⁻ and χcJ→pn̄π⁻π⁰ (J=0, 1, 2) are measured. (Throughout the text, inclusion of charge conjugate modes is implied if not stated otherwise.) The results for χc⁰→pn̄π⁻ and χ→pn̄π⁻ are consistent with, but much more precise than, those of previous measurements. The decays of χc1→pn̄π⁻ and χcJ→pn̄π⁻π⁰ are observed for the first time.
