  Galaxy rotation curves determined observationally out to a radius well beyond
the galaxy cores can provide a critical test of modified gravity models without
dark matter. The predicted rotational velocity curve obtained from
Scalar-Vector-Tensor Gravity (STVG or MOG) is in excellent agreement with data
for the Milky Way without a dark matter halo, with a mass of $5\times
10^{10}\,M_{\odot}$. The velocity rotation curve predicted by modified
Newtonian Dynamics (MOND) does not agree with the data.
