Recent results on vector-like quarks and excited fermions at CMS

The most recent results on the searches for the vector-like quarks and excited fermions from the CMS Collaboration are presented. These results are based on the full Run 2 $\sqrt{s}=$13 TeV proton-proton collision data collected by the CMS Collaboration at the LHC from 2016 to 2018, which corresponds to an integrated luminosity of 138 fb${}^{-1}$. No significant excess above the Standard Model expectation is observed. Exclusion limits are set at the 95% confidence level on various benchmark models.
