Abstract
A completely non-perturbative estimate is given for the u/d and strange quark masses in quenched QCD using O(a) improved fermions and, for comparison, Wilson fermions. For improved fermions we find m_{u/d}^MSbar(\mu=2 GeV) = 4.4(2) MeV, m_s^MSbar(\mu=2 GeV) = 105(4) MeV when using r_0 to set the physical scale.
