Abstract
The physics impact of a precise determination of the top-quark mass, mt, at the Linear Collider (LC) is discussed, and the results are compared with the prospective accuracy at the LHC. The importance of a precise knowledge of mt for electroweak precision observables and for Higgs physics in the MSSM is pointed out in particular. We find that going from hadron collider to LC accuracy in mt leads to an improvement of the investigated quantities by up to an order of magnitude.
