We present a catalogue of velocities for 466 galaxies in the direction of the cluster Abell 496, in a region covering about $160'\times 160'$( $9.2\times9.2$ Mpc for an average redshift for Abell 496 of 0.0331, assuming H0 = 50 km s-1 Mpc-1). This catalogue includes previously published redshifts by Proust et al. (1987), Quintana & Ramírez (1990) and Malumuth et al. (1992), redshifts from the CfA redshift survey, together with our new measurements. A total of 274 galaxies have velocities in the 7800-11800 km s-1 interval, and will be considered as members of the cluster. Abell 496 therefore becomes one of the few clusters with a high number of measured redshifts; its physical properties are investigated in a companion paper.
