Zinner is a tiny lunar impact crater located due north of the crater Schiaparelli on the Oceanus Procellarum. It is circular and cup-shaped, with a high albedo in comparison to the surrounding lunar mare. The crater lies across a linear ray from the southwest. To the northwest is the slightly larger crater Golgi. East of Zinner is the Dorsa Burnet wrinkle ridge system.
This feature was previously designated Schiaparelli B before being given a name by the IAU.
