The cross sections for Co(n,xp) reactions have been determined in the equivalent neutron energy range of 11.7–16.8 MeV by employing the surrogate reaction ratio method and using the cross-section values for the reference reaction 
Ni(n,xp) from the literature. The transfer reactions 
Fe(
Li,
) at 
= 37 MeV and 
Co(Li,) at = 33 MeV, are used to populate compound nuclei Co
(surrogate of n+Co) and 
Ni (surrogate of n+Ni), respectively, at similar excitation energies. The evaporated protons at backward angles measured in coincidence with the projectile-like fragment alpha provide the proton decay probabilities of the compound nuclei. The cross sections estimated using the nuclear-reactions-model code talys-1.96 are consistent with the experimental Co(n,xp) data for the entire neutron energy range. However, the predictions of the evaluated data libraries endf/b-viii, jeff-3.3, jendl-5, rosfond-2010 and tendl-2019 overestimate the present experimental data, indicating the necessity to improve the model parameters of the data libraries for this reaction.
