Poisson is a lunar crater that is located in the southern highlands of the Moon's near side. It lies to the east of Aliacensis crater and northwest of Gemma Frisius. To the northwest of Poisson is the Apianus crater.
This heavily-eroded crater shares a common floor with the satellite crater 'Poisson T' to the west-southwest, and the two craters have more or less merged into a single formation with a narrower neck in between. The rim of Poisson is heavily eroded, and is overlaid by several craters. 'Poisson U' is intruding into the southern rim at the junction of Poisson and 'Poisson T'. A low-walled formation is joined to the northern rim at the opposite side of the neck from 'Poisson U.
The interior floor of Poisson and 'Poisson T' has been resurfaced by basaltic-lava, leaving a level surface within the inner walls. A pair of old, worn craters lie along the inner wall in the southeast part of the crater.

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 Poisson crater.
