Recent results on exotic spectroscopy from the LHCb experiment are introduced in these proceedings. They contain the evidence for a new pentaquark candidate decaying to $J/\psi p$ and $J/\psi \bar{p}$ in the $B^0_s\to J/\psi p \bar{p}$ decays and the observation of four new resonances decaying to $J/\psi K^+$ and $J/\psi\phi$ in the $B^+ \to J/\psi \phi K^+$ decays, two of which are tetraquarks with strangeness.
