We summarize the current top quark mass (m_t) measurements from the CDF and D0 experiments at Fermilab. We combine published results from Run I (1992–1996) with the most precise published and preliminary Run II (2001–2011) measurements based on $$p\bar{p}$$ data corresponding to up to 9.7 fb^$$-$$1 of $$p\bar{p}$$ collisions. Taking correlations of uncertainties into account, and combining the statistical and systematic contributions in quadrature, the preliminary Tevatron average mass value for the top quark is m_t = 174.30 ± 0.65 GeV/c², corresponding to a relative precision of 0.37%.
