Measurements of top quark properties with the CMS experiment

Measurements of properties of the top quark with the CMS experiment at the CERN LHC are presented. Top quark pair production events at $\sqrt{s}=13\,\text{TeV}$ are used to measure the top quark Yukawa coupling, to study the spin correlation between the top quarks, and to extract the forward-backward asymmetry in quark-antiquark initiated production. A combination of the measurements of W boson polarization in top quark pair and single top quark production events at $\sqrt{s}=8\,\text{TeV}$ performed by the ATLAS and CMS experiments is shown. A first direct measurement of the elements of the CKM matrix involving the top quark is performed in single top quark production events at $\sqrt{s}=13\,\text{TeV}$.
