This note presents an analysis of the potential of future high-energy electron-positron colliders to measure the b-quark mass. We perform a full-simulation study of the measurement of the ratio of the three-jet rates in events with bb(g) and qq(g) production, R3bl, and assess the dominant uncertainties, including theory and experimental systematic uncertainties. We find that the ILC "Higgs factory" stage, with an integrated luminosity of 2 ab-1 at √(s)= 250 GeV can measure the b-quark barMS mass at a scale of 250 GeV (mb(250~GeV)) with a precision of 1 GeV. From this result we extrapolate the potential of the GigaZ run running at √(s)= mZ. We expect mb(mZ) can be determined with an 0.12 GeV uncertainty, exceeding the precision of the LEP and SLD measurements by a factor ∼3.
