We summarize the current top-quark mass measurements from the CDF and D0 experiments at Fermilab. We combine published Run I (1992--1996) results with the most precise published and preliminary Run II (2001--2011) measurements based on 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 uncertainties, the resulting preliminary Tevatron average mass of the top quark is $$M_{top} = 174.34 \pm 0.64 ~GeV/c^2$$, corresponding to a relative precision of 0.37%.
