Teisserenc is an eroded lunar impact crater on the Moon's far side.

The outer rim of this crater has become eroded due to subsequent impacts.

The remainder of the rim is somewhat uneven, especially at the southern end where it has been damaged by small impacts.

There is an unusual area of level ground to the south of Teisserenc, which stands in contrast with the battered terrain that surrounds the crater in the other directions.

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