  We determine the masses of the light and the strange quarks in the
$\bar{MS}$-scheme using our high-statistics lattice simulation of QCD with
dynamical Wilson fermions. For the light quark mass we find
$m^{light}_{\bar{MS}}(2 GeV) = 2.7(2) MeV$, which is lower than in quenched
simulations. For the strange quark, in a sea of two dynamical light quarks, we
obtain $m^{strange}_{\bar{MS}}(2 GeV) = 140(20) MeV$.
