Poinsot is a worn lunar crater that is located at the northern part of the Moon on the far side. It lies to the south of the Rozhdestvenskiy walled-plain. To the south is the smaller Heymans crater.

This formation has been heavily worn by subsequent impacts, leaving a round-shouldered outer rim that is nearly even with the surrounding terrain and an inner surface that slopes down to the floor without s or horizontal features. A number of tiny craterlets lie along the rim edge and inner walls, as well as across the level interior surface. The floor lacks a central peak at the mid-point, but has a small but notable crater lying next to the western inner wall.

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 Poinsot crater.
