Sumario:We present a review of recent results from the CMS experiment on top quark physics. CMS performed measurements of top quark mass, charge, and decay properties, $\mathrm{t\bar{t}}$ and single top quark production cross sections in several channels, as well as measurements of differential production cross sections and $\mathrm{t\bar{t}}$ production properties: charge asymmetry, spin correlations and top quark polarization. For the first time the cross section ratio $\sigma_{\,\mathrm{t\bar{t} b\bar{b}}} / \sigma_{\,\mathrm{t\bar{t} jj}} $ and the cross section of $\mathrm{t\bar{t}}$ in association with W and Z bosons have been measured. CMS established evidence of the W-associated single top quark production. Most of the measurements have uncertainties dominated by systematic effects. All of the results are found to be consistent with the standard model predictions.
