The two--point velocity correlation is not a useful indicator of a non--Gaussian density field, since it depends only on the power spectrum, even for non--Gaussian models. However, we show that the distribution of velocity differences $\\bfv_1 - \\bfv_2$, where $\\bfv_1$ and $\\bfv_2$ are measured at the points $\\bfr_1$ and $\\bfr_2$, respectively, is a good probe of non--Gaussian behavior, in that $p(\\bfv_1 - \\bfv_2)$ tends to be non--Gaussian whenever the density field is non--Gaussian.
