  The measured proper motion of Fornax, expressed in the equatorial coordinate
system, is $(\mu_{\alpha},\mu_{\delta})=(47.6\pm 4.6,-36.0\pm 4.1)$ mas
century$^{-1}$. This proper motion is a weighted mean of four independent
measurements for three distinct fields. Each measurement uses a quasi-stellar
object as a reference point. Removing the contribution of the motion of the Sun
and of the Local Standard of Rest to the measured proper motion produces a
Galactic rest-frame proper motion of $(\mu_{\alpha}^{\mbox{\tiny{Grf}}},
\mu_{\delta}^{\mbox{\tiny{Grf}}}) = (24.4\pm 4.6,-14.3\pm 4.1)$ mas
century$^{-1}$. The implied space velocity with respect to the Galactic center
has a radial component of $V_{r}=-31.8 \pm 1.7$ km s$^{-1}$ and a tangential
component of $V_{t}=196 \pm 29$ km s$^{-1}$. Integrating the motion of Fornax
in a realistic potential for the Milky Way produces orbital elements. The
perigalacticon and apogalacticon are 118 (66, 137) kpc and 152 (144, 242) kpc,
respectively, where the values in the parentheses represent the 95% confidence
intervals derived from Monte Carlo experiments. The eccentricity of the orbit
is 0.13 (0.11, 0.38), and the orbital period is 3.2 (2.5, 4.6) Gyr. The orbit
is retrograde and inclined by $101^{\circ}$ ($94^{\circ}$, $107^{\circ}$) to
the Galactic plane. Fornax could be a member of a proposed ``stream'' of
galaxies and globular clusters, however the membership of another proposed
galaxy in the stream, Sculptor, has been previously ruled out. Fornax is in the
Kroupa-Theis-Boily plane that contains eleven of the Galactic satellite
galaxies, but its orbit will take it out of that plane.
