The LHC, producing huge amount of $b\bar{b}$ and $c\bar c$ pairs, is the ideal place for spectroscopy studies which are fundamental as tests and inputs for QCD models. Many of the recently observed states, which are not fitting the standard picture, are still lacking of interpretation. A wide range of interesting spectroscopy measurements have been performed by the LHC experiments, ATLAS, CMS and LHCb. Only a selection of recent results are reported here. Many new and striking results are expected with the starting of the data taking in 2021 after the Long Shutdown 2 of the LHC.
