Seyfert is a prominent lunar impact crater that is located on the far side of the Moon. It lies behind the eastern limb of the Moon, to the east of Espin crater. Just to the north of Seyfert is the Harriot crater and equally close to the south is Polzunov crater.

The outer rim of this crater is slightly elongated to the north, and the northeastern rim is overlaid by the satellite crater 'Seyfert A'. This overlapping impact crater has a central ridge of its interior floor. There is a low ridge near the mid-point of Seyfert crater, but it is less prominent. The inner wall of Seyfert crater is wider along the northern edge, west of 'Seyfert A'.

Several small craters lie along the rim and interior of Seyfert, including a merged group of small craters along the eastern inner wall, a small crater intruding into the southeastern rim, and a pair of small craters along the southern rim of 'Seyfert A'. The interior floor of Seyfert is relatively level, and is marked by a number of tiny craterlets. Traces of the ray system from the Giordano Bruno crater to the northwest lie along the rim and interior floor of Seyfert.

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 Seyfert crater.
