Biela is a lunar impact crater that is located in the rugged highlands of the southeastern Moon. It is named after Austrian astronomer Wilhelm von Biela.^[1] The crater lies to the east of Rosenberger, to the southeast of the Watt–Steinheil double crater.

The rim of this crater is overlaid by a pair of small but notable craters: Biela C across the northeast rim and Biela W along the western inner wall. The satellite crater Biela B is attached to the southwestern outer rim, and ejecta from Biela covers the northwestern part of the interior. Despite a certain degree of wear, the rim of Biela remains relatively well-defined, especially in the southeast.

The interior floor is flat and not marked by any craterlets of note. There is a central peak formation of three ridges located just to the northeast of the midpoint.
