Triesnecker is a prominent lunar impact crater that is located in the Sinus Medii, near the central part of the Moon's near side. It is located to the north-northwest of the Rhaeticus crater, and to the east-southeast of the flooded Murchison crater.
The crater rim of Triesnecker is somewhat distorted from a circular shape, having a notable bulge in the western wall, and lesser rises in the southeast and northeast rims. The inner walls are terraced and the interior is somewhat rough, with a central peak at the mid-point. Triesnecker has a ray system that is most prominent when the sun is at a high angle. The rays extend over 300 kilometers.
To the east of this crater is an extensive system of rilles extending over an area 200 kilometers across, running generally north-south. These were likely created by tectonic forces beneath the surface. Beyond, to the northeast, is the Rima Hyginus valley, with the Hyginus crater at the mid-point.

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 Triesnecker crater.
