The distribution of nearly 1300 OB stars with galactocentric azimuths θ between 170° and 290° is used to search for evidence of a stellar warp in the southern Milky Way. Consistent with observations of the H I disk, clear evidence is obtained of a warp reaching to ζ≍-1.5 kpc at R≍15 kpc, θ≍240-280.
