The most recent LHCb results related to heavy hadron spectroscopy, encompassing both conventional and exotic states, have been reported. These results include the observation of new $\Omega_c^0$ states, the first observation of a doubly charged tetraquark candidate and its neutral partner, the observation of a $c\bar{c}s\bar{s}$ candidate, $X(3960)$, evidence of a neutral hidden-charm tetraquark candidate with strangeness, and the first observation of a strange pentaquark candidate, $P_{\psi s}^\Lambda(4338)^0$.
