Recent lattice QCD studies of charmonium-like and bottomonium-like states will be presented. The masses and widths of charmonium-like states with isospin zero are extracted by considering the scattering on the lattice. We find conventional charmonia with J=0,1,2,3 in line with experiment and two exotic candidates just below D barD and Ds barDs thresholds. The bottomonium-like system with isospin one is studied with static b quarks and shows an indication for the Zb resonance.
