Poisson is a lunar impact crater that is located in the southern highlands of the Moon's near side. It was named after French mathematician Siméon Denis Poisson.[1] It lies to the east of the crater Aliacensis and northwest of Gemma Frisius. To the northwest of Poisson is Apianus.

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 overlain 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 lies along the inner wall in the southeast part of the crater.

## Satellite craters

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