Moiseev is a lunar impact crater that is located just on the far side of the Moon. It lies to the south-southwest of the slightly larger crater Hertz, and north of Saenger. To the southeast lies the irregular crater Al-Khwarizmi.
Moiseev overlies the southern rim of the larger satellite formation Moiseev Z. The crater is not significantly worn, and is marked only by a few tiny craterlets in the interior. The rim is generally circular, but has an outward bulge and a wider interior wall to the west-southwest. There are some terrace structures around the inner eastern wall, while the western inner wall has more of a slumped appearance. At the midpoint of the flattened interior is a formation of low hills forming the crater's central peak complex.
Prior to naming in 1970 by the IAU, Moiseev was known as Crater 198, and Moiseev Z was known as Crater 197.
