The CFHT was used to obtain high-resolution CCD images of 82 cluster candidates in the halo of M31. These data, combined with radial velocities which cover an additional 27 candidates, are used to compile a catalog of 51 bona fide M31 halo globulars. The other candidates are found to be background galaxies (54) and field stars (4). The cluster sample appears to be incomplete for V>18. The projected distribution of globulars follows an r^2^ law for 6<r(kpc)<22 and then drops faster, suggesting a cutoff at ~40 kpc. These trends are similar to those for globular clusters in the Milky Way halo. The total population of globulars in M31 is estimated to be larger than in the Milky Way by a factor of 1.8+/-0.3.
