Abstract: We study the SU(3) gluon propagator in renormalizable R_ξ gauges implemented on a symmetric lattice with a total volume of (3.25  fm)^4 for values of the gauge fixing parameter up to ξ=0.5. As expected, the longitudinal gluon dressing function stays constant at its tree-level value ξ. Similar to the Landau gauge, the transverse R_ξ gauge gluon propagator saturates at a nonvanishing value in the deep infrared for all values of ξ studied.
