Abstract: Exotic hadrons, which are composed of more than three valence quarks, can provide new insights into the internal structure and dynamics of hadrons, thus improving our knowledge of the non-perturbative regime of QCD. Since 2003, various candidates for exotic states have been observed, to which the LHCb experiment has made major contributions. This seminar discusses the studies on exotic hadrons at LHCb. The most recent results on $\chi_{c1}(3872)$ lineshape study and observation of structure in the $J/\psi$-pair invariant mass spectrum are presented.
