Polarized scattered light from the non-transiting hot Jupiter $\\upsilon$~And~b is measured to further constrain its orbit, mass, density, and geometrical albedo. We obtained polarimetric measurements in the $UBV$ bands over the orbital period and deduce an average peak-to-peak amplitude of $(49 \\pm 5)\\times10^{-6}$ in both Stokes $q$ and $u$.
