Top physics results with ATLAS

Top quark are the most massive known particles of the Standard Model, and they have the unique property to decay before the hadronization process. During Run I ATLAS has provided several top quark measurements to make stringent tests on Standard Model. In this talk the most recent results of the analysis about top quark will be presented; in particular: $t\bar{t}$ inclusive and differential cross section, single top cross section, $t\bar{t}+\gamma$ associate production cross section, top quark mass, $t\bar{t}$ charge asymmetry and spin correlation. Even if most of the measurements are limited by systematic uncertainties, all results agree with the Standard Model.
