Abstract:We report the 6dFGS Fundamental Plane (6dFGSv) catalogue that is used to estimate distances and peculiar velocities for nearly 9000 early-type galaxies in the local (z<0.055) universe. Velocity dispersions are derived by cross-correlation from 6dF V-band spectra with typical S/N of 12.9{AA}^-1^ for a sample of 11315 galaxies; the median velocity dispersion is 163km/s and the median measurement error is 12.9 per cent. The photometric Fundamental Plane (FP) parameters (effective radii and surface brightnesses) are determined from the JHK 2MASS images for 11102 galaxies. Comparison of the independent J- and K-band measurements implies that the average uncertainty in X_FP_, the combined photometric parameter that enters the FP, is 0.013dex (3 per
