Results on Charmonium and Charmonium-like States at the Belle Experiment

New results of the Belle experiment at the KEKB asymmetric e^+e^- collider are presented, in particular (a) measurement of the mass and width of the ${\eta }_c$ and ${\eta }_c^{\mathrm{\prime }}$ in B meson decays, (b) measurement of the mass, width and quantum numbers of the X(3872) and © observation of the ${\chi }_{c2}$ in $B$ meson decays.
