Tsu Chung-Chi is a relatively small lunar impact crater on the Moon's far side.

It lies to the west-southwest of the crater Leonov, and to the northeast of the large walled plain Mendeleev.

It has undergone some erosion, with a small, cup-shaped crater intruding slightly into the southern rim and several tiny craterlets within the interior.

According to the memoirs of Boris Chertok, who was closely involved with the Luna 3 mission, some fairly complicated politics was involved in picking the name: Finally, the Keldysh Commission received a go-ahead, and obtained a decision of the Praesidium of the Academy to name the craters after prominent scientists and cultural figures: Giordano Bruno, Jules Verne, Hertz, Kurchatov, Lobachevsky, Maxwell, Mendeleev, Pasteur, Popov, Skłodowska-Curie, Zu Chongzhi and Edison.

[2] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Tsu Chung-Chi.
