The present report summarizes recent CMS results in conventional and exotic hadron spectroscopy, obtained using the data collected at the Large Hadron Collider during the Run-2 data taking (2015-2018) either with proton-proton collisions at $\sqrt{s} = 13$~TeV or lead-lead collisions at $\sqrt{s_{NN}}$ = 5.02~TeV per nucleon pair. The results include the first observation of the $B_s^0 \rightarrow X(3872)\phi$ decay mode, evidence of X(3872) production in lead-lead collisions, a search for intermediate resonances in the $B^0 \rightarrow \psi(2S)K_s^0\pi^+\pi^-$ multi-body decay, and the observation of $\Lambda_b^{**}$ and $\Xi_b^{**}$ excited states. |
