Zanstra is a lunar impact crater that is located on the far side of the Moon and is named after the Dutch astronomer Herman Zanstra. It lies to the southeast of the crater pair Ibn Firnas and King, southwest of Morozov, and northwest of Gregory. This is a low, eroded formation that is difficult to distinguish from its surroundings. The interior floor is level and not significantly impacted.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Zanstra.
