Abstract : The Cosmicflows database of galaxy distances that in the 2nd edition contained 8,188 entries is now expanded to 17,669 entries. The major additions are 2,257 distances that we have derived from the correlation between galaxy rotation and luminosity with photometry at 3.6 microns obtained with Spitzer Space Telescope and 8,885 distances based on the Fundamental Plane methodology from the 6dFGS collaboration. There are minor augmentations to the Tip of the Red Giant Branch and Type Ia supernova compilations. A zero point calibration of the supernova luminosities give a value for the Hubble Constant of 76.2 +-3.4(r) +-2.7(s) km/s/Mpc. Alternatively, a restriction on the peculiar velocity monopole term representing global infall/outflow implies H_0 = 75 +-2 km/s/Mpc.
