The recent results on charm and charmonium spectroscopy obtained by the LHCb collaboration are reviewed. In particular, observation of new charmonium state in the decay modes X(3842) → D0D−0 and X(3842) → D+D−, evidence for ηc(1S)π− resonance in B0 → ηc(1S)K+π− decay and observation of three narrow P+c pentaquark candidates decaying to J/ψp are obtained. Also, lifetimes of Ξ+c, Λ+c, Ξ0c and Ω0c baryons are measured with high precision.
