Orlov is a lunar impact crater. It is located on the Moon's far side, to the northeast of the larger crater Leeuwenhoek. To the north-northwest of Orlov is De Vries, and to the east-southeast is Rumford.
This crater lies between two larger satellite craters. Orlov Y is attached to the northern rim, and Leeuwenhoek E is connected along the southwest. The latter is also the location of an outward bulge in the rim of Orlov, giving it a wider interior wall along that side. There is some terracing along the eastern inner wall of Orlov. Orlov D, an oval-shaped crater, is attached to the outer rim along the northeast.
The interior floor of Orlov is relatively level with a central ridge formation located near the midpoint. There are some small craters along the extended inner wall to the southwest.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Orlov.

Ewen Adair Whitaker was a British-born astronomer who specialized in lunar studies. During World War II he was engaged in quality control for the lead sheathing of hollow cables strung under the English Channel as part of the "Pipe Line Under The Ocean" Project (PLUTO) to supply gasoline to Allied military vehicles in France. After the war, he obtained a position at the Royal Greenwich Observatory working on the UV spectra of stars, but became interested in lunar studies. As a sideline, Whitaker drew and published the first accurate chart of the South Polar area of the Moon in 1954, and served as director of the Lunar Section of the British Astronomical Association.
