We measure the clustering of DES Year 1 galaxies that are intended to be combined with weak lensing samples in order to produce precise cosmological constraints from the joint analysis of large-scale structure and lensing correlations. Two-point correlation functions are measured for a sample of 6.6×10 5 luminous red galaxies selected using the \textsc{redMaGiC} algorithm over an area of 1321 square degrees, in the redshift range 0.15 0.5 , b(z =0.68)=1.93±0.05 for L/L * > 1 and b(z =0.83)=1.99±0.07 for L/L * >1.5 , broadly consistent with expectations for the redshift and luminosity dependence of the bias of red galaxies. We show these measurements to be consistent with the linear bias obtained from tangential shear measurements.
