Tiselius is a lunar impact crater that lies just to the east of the Valier crater, on the Moon's far side. The craters Tiselius and Valier are separated by only a few kilometers of intervening terrain. Less than a crater diameter to the east of Tiselius is the smaller, elongated Stein crater, and to the north is the small, eroded Šafařík crater.

This is a roughly circular crater with a well-defined edge that has not been significantly degraded by impact erosion. The inner walls have slumped in places to form piles of scree. The interior floor is marked by a few small craterlets, and there is an irregular group of ridges around the mid-point. The small, cup-shaped satellite crater 'Tiselius E' lies near the eastern outer edge.

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 Tiselius crater.
