Trumpler is a lunar crater on the far side of the Moon, named after Robert Julius Trumpler. It lies just to the south of Nušl crater, and northwest of Freundlich crater. To the southwest is the heavily battered Tikhomirov crater.

This is an old, eroded crater with an outer rim that has been damaged in places by subsequent impacts, especially along the southwestern section. The rim edge has been worn to the point where it is now poorly defined, and forms an uneven ridge in the surface. A short chain of small craterlets extends from near the crater mid-point to just outside the eastern rim. The southern interior floor is generally less impacted in the northern half.

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 Trumpler crater.
