Abstract
The mass of the top quark is a fundamental parameter of the standard model (SM) and has to be determined experimentally. The D0 experiment at the Fermilab Tevatron proton-antiproton collider with a centre-of-mass energy of 1.96 TeV has measured the top quark in various channels. In this talk, I present the most recent measurements of the top quark mass in the dilepton and lepton+jets channels with up to 5.3 \fb\ as well as their combination, and give an outlook on the final, most precise measurement of the top quark mass at D0.
