In the present article, we employ the Regge phenomenology to describe the mass-spectra of singly charmed baryons. With the assumption of linear Regge trajectories, the relations between Regge slopes, intercepts, and baryon masses are derived. Using these relations we evaluated the Regge slopes (
) for 
, 
, 
, 
, and 
baryons and obtain the orbitally excited state masses in the 
plane. Similarly, the Regge parameters (
and 
) are estimated for each Regge line in the 
plane and the radially excited state masses are obtained. Also, the experimental errors are calculated in the obtained results wherever the experimental inputs are taken. Further the Regge trajectories are plotted for our calculated masses in the (
) plane. We compared our estimated results with the experimental data and other theoretical predictions. We assign the spin–parity of recently observed experimental states
