Timiryazev is a lunar impact crater that is located just to the east of the huge walled plain Korolev, on the far side of the Moon.

It lies to the west-northwest of the crater Sechenov and north-northeast of Mechnikov.

This is a circular crater formation with a slightly eroded outer rim and interior, and an interior floor that is about half the diameter of the crater.

The interior is relatively featureless, with only some slight irregular areas on the floor.

[1] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Timiryazev.
