  The jet quenching parameter of an anisotropic plasma depends on the relative
orientation between the anisotropic direction, the direction of motion of the
parton, and the direction along which the momentum broadening is measured. We
calculate the jet quenching parameter of an anisotropic, strongly coupled N=4
plasma by means of its gravity dual. We present the results for arbitrary
orientations and arbitrary values of the anisotropy. The anisotropic value can
be larger or smaller than the isotropic one, and this depends on whether the
comparison is made at equal temperatures or at equal entropy densities. We
compare our results to analogous calculations for the real-world quark-gluon
plasma and find agreement in some cases and disagreement in others.
