Sinus Roris (latin for "Bay of Dew") is an extension of the northern edge of Oceanus Procellarum on the Moon. The IAU-defined selenographic coordinates of this bay are 54.0° N, 56.6° W, and the diameter is 202 km. The borders of this feature are somewhat indistinct. The bay proper is framed along the western edge by the craters Markov and Oenopides, and to the north by Babbage and South. At the eastern edge it joins the Mare Frigoris.
