Bečvář (Czech pronunciation: [ˈbɛtʃvaːr̝̊]) is a lunar crater that is located near the equator on the far side of the Moon from the Earth. It lies to the northeast of the crater Necho, within that feature's ray system. To the north-northeast is the crater Gregory.

This is a worn, eroded crater system with a few tiny craterlets lying across the floor and rim. A double-crater formation occupies the southwestern rim, with Bečvář Q forming the northwestern member of this pair. The crater Bečvář X is attached to the northern rim.
