Bečvář (IPA: [ˈbɛtʃva:r̝̊]) 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 Necho crater, within that crater's ray system. To the north-northeast is the Gregory crater.

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.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Bečvář crater.
