A summary of results for the top quark charge asymmetry, $\text{A}_{\text{C}}$, measured using 20.3 fb$^{-1}$ of data recorded with the ATLAS detector at a center-of-mass energy $\sqrt{s}=8$ TeV is presented. Events where either both top quarks decay leptonically (dileptonic), or one top quark decays leptonically and the other hadronically (semi-leptonic) are considered. The semi-leptonic channel is split into a boosted analysis, where the top decay products overlap in the detector, and a resolved analysis, where the top decay products are well-separated in the detector. All analyses fully reconstruct the $t\bar{t}$ system and apply an unfolding procedure to estimate $\text{A}_{\text{C}}$ at the parton level. All measurements are consistent with Standard Model predictions.
